1. In a rare coin collection, there is one gold coin
for every three non-gold coins. 10 more gold coins are added to the collection
and the ratio of gold coins to non-gold coins would be 1:2. Based on the
information, the total number of coins in the collection now becomes
(a)90 (b)80 (c)60 (d)50
Solution:
Initial ratio =
G:N = 1:3 ---(1)
After adding 10
gold coins, the ratio becomes (10+G):N =
1:2 ---(2)
On solving (1)
& (2), we get, G=20 and N=60.
Presently, the
total number of coins in the collection = (10+G)+N= 10+20+60=90
Ans: (a)
2. A gardener has 1000 plants. He wants to plant them
in such a way that the number of rows and the number of columns remains the
same. What is the minimum number of plants that he needs more for this purpose?
(a)90 (b)24 (c)32 (d)34
Solution:
If the number of
rows and number of columns are to be equal, then the total number of trees will
be in the form of x2, which is nothing but a perfect square. As 1000
is not a perfect square, we need to check for a perfect square above and
nearest to 1000.
It’s 1024, which
is square of 32. So he needs to add 24 more trees to get 1024.
Ans: (b)
3. A Sum of Rs 700 has to be used to give 7 cash
prizes to the student of a school for their overall academic performance. If
each prize is Rs 20 less than its preceding
price, what is the least value of the price?
(a)Rs
30 (b)Rs 40 (c)Rs 60 (d)Rs 80
Solution:
Let the least
value price be X. Then the next value is X+20, and the next value is X+40 and
on and on up to 7 values.
It’s nothing but
an arithmetic Progression with sum 700.
X + X+20 + X+40
+… X+120=700 => 7X+(20+40+…+120)=700
=>
7X+20(1+2+3+…+6)=700 => 7X+20(21)=700 => 7X=280 =>X=40
Ans: (b)
4. Out of 120 applications for a post 70 are male and
80 have a driver’s license. What is the ratio between the minimum to maximum
number of males having driver’s license?
(a)1
to 2 (b) 2 to 3 (c)3 to 7(d)5 to 7
Solution:
70 male =>
120-70=50 female
For a maximum, all 70 male shall have driver’s
license
For a minimum:
If all 50 females posses driver’s license, then the remaining 30 licenses shall
be possessed by males. So minimum male-driver’s licenses = 30
Min to max = 30
to 70 = 3 to 7
Ans: (c)
5. In a garrison, there was food for 1000 soldiers for
one month. After 10 days, 1000 more soldiers joined the garrison. How long
would the soldiers be able to carry on with the remaining food?
(a)25
days (b) 20 days (c) 15 days (d) 10 days
Solution:
After 10 days,
the remaining food would be sufficient for the 1000 soldiers for 20 more days
=> If 1000
more soldiers are added, it shall be sufficient for only 10 days (as the no. of
soldiers is doubled, the days are halved)
Ans: (d)
6. A tank-full petrol in Arun’s motor-cycle last for
10 days. If he starts using 25% more every day, how many days will the tank-full
petrol last?
(a)5
(b) 6 (c) 7 (d) 8
Solution:
The analogy is
like this: Arun has 10 lt of petrol and he uses 1 lt per each day and consumes
it in 10 days. If he uses 1.25 lt every day, in how many days it will be
consumed?
We considered
1.25 lt here because it’s 25% more than 1 lt.
The answer would
be 10/1.25=8
Ans: (d)
7. A person can walk a certain distance and drive back
in 6 hrs. He can also walk both ways in 10 hrs. How much time will he take to
drive both ways?
(a)Two
hours (b) Two and a half hours (c) Five and a half hours (d) Four hrs
Solution:
2-way walk = 10
hrs => 1-way walk = 5 hrs
1-way walk +
1-way Drive = 6 hrs => 1-way drive = 6-5= 1 hr
Hence, 2-way
drive = 2 hrs

whose speed is 10km/hr. If the thief is 100m ahead of policeman, then the time
required for the policeman to catch the thief will be?
(a)2
(b) 3 (c) 4 (d) 6
Solution:
If we consider
the difference of speeds, policeman is at 2 km/hr leading speed and hence he
can catch the thief at 100m ahead by 100m/2kmph = 100/2000 hr = 3 min
Ans: (b)
14. A train travels at a certain average speed for a
distance of 63 km and then travels a distance of 72 km at an average speed of 6
km/hr more than its original speed. If it takes 3 hours to complete the total
journey, what is the original speed of the train in km/hr?
(a)24
(b) 33 (c) 42 (d) 66
Solution:
Let the original
speed be ‘S’.
Total time taken
= 3 hr => 63/S + 72/S+6 = 3
Let us try with
answer options. As we have 63 in the numerator, we can assume that S may be a
multiple of 7. The only option available
is 4. So, let us try with that.
63/42 + 72/48 =
3/2 + 3/2 = 3 => this suits

Which car
maintained the maximum speed?
(a)
Car A (b) Car B (c) Car C (d) Car D
Solution:
Let the
distances travelled by cars A,B,C and D be a,b,c and d respectively.
Then, total payment for car A = 6a+40(a/8) =
11a=2120 => a=2120/11
It is mentioned
that car A travels for 20 hr
=> The
average speed of A= a/20 = 2120/11*20 = 106/11 > 9
Equation for B: 6b+40(b/10)=1950 => b=195
=> The
average speed of B= b/25 = 195/25 = 39/5=7.8
Equation for C:
6c+40(c/9)=2064 => c=9*1032/47
=> The
average speed of C= c/24 = 9*43/47 < 9
Equation for D:
6d+40(d/11)=1812 => d=11*906/53
=> The
average speed of D= d/22 = 453/53 < 9
All speeds
except for A are less than 9 where as seed for A is greater than 9 and hence
it’s the greatest value.

19. Seven men A,B,C,D,E,F and G are standing in a
queue in that order. Each one is wearing a cap of different colour like
violet,indigo,blue,green,yellow,orange and red. D is able to see in front of
him green and blue, but not violet. E can see violet and yellow but not red. G
can see caps of all colours other than orange. If E is wearing an indigo
coloured cap, then the colour of cap worn by F is
(a)Blue
(b)Violet (c) Red (d) Orange
Solution:
Order: A,B,C,D,E,F, G
The point is – A person can see caps of
all persons standing in front of him but can’t see his own cap and caps of
persons standing behind him.
D is able to see
in front of him green and blue, but not violet => The people in front of D
ie., A or B or C worn green or blue and people after D and including himself
ie., D or E or F or G worn violet
E can see violet
and yellow but not red => From this and above statements, we can fix violet
cap for D. and A/B/C worn green/blue/yellow not necessarily in that order
G can see caps
of all colours other than orange => As he is the last person in the row, he
can see all caps except his. So we can fix Orange cap for G
Given that E
wears indigo cap.
The summary is:
Person
|
Cap
|
A/B/C
|
green/blue/yellow
|
D
|
violet
|
E
|
indigo
|
G

starting from Q, but without changing the mode of transport?
(a)Boat
(b)Rail (c) Bus (d) Air
Solution:
We have the
following transport options:
Q to P and P to
R: Here boat is a common mode of transport and this seems to be the correct
answer. But let us check the other transportation.
Q to T and T to
R : Here Q and T are connected by air only and T and R are connected by rail
and bus To make a complete trip there is no single mode of transport. So, this option is ruled out.
Here we have
only one rout Q-P-R which has a single mode of transportation ie., Boat
Ans: (a)
22. If a person visits each of the places starting
from P and gets back to P, which of the following places must he visit twice?

It
was already late when we set out for the next town, which according to the map
was about fifteen kilometers away on the other side of the hills. There we felt
that we would find a bed for the night. Darkness fell soon after we left the
village but luckily we met no one as we drove swiftly along the narrow winding
road that led to the hills. As we climbed higher, it became colder and rain
began to fall, making it difficult at times to see the road. I asked John , my
companion to drive slowly. After we had travelled for about twenty kilometers,
there was still no sign of the town which was marked on the map. We were
beginning to get worried. Then without warning the car stopped and we found we
had run out of petrol.

A
stout old lady was walking with her basket down the middle of a street in
Petrograd to the great confusion of traffic and no small peril of herself. It
was pointed out to her that the pavement was the place for foot-passengers, but
she replied, “I am going to walk where I like. We have got liberty now.” It did
not occur to the dear lady that if the liberty entitled the foot-passenger to
walk down the middle of the road, it also entitled the taxi driver to drive on
the pavement, and that the end of such liberty would be universal chaos.
Everything would be getting in everybody else’s way and nobody would get
anywhere. Individual liberty would have become social anarchy.
37. It was pointed out to the lady that she should
walk on the pavement because she was
(a) a pedestrian.
(b)
carrying a basket.
(c)
stout.
(d)
an old lady.
Solution:
Pavement is for
pedestrians. As she is walking, she is pointed to use pavement.
Ans: (a)
38. The lady refused to move from the middle of the
street because
(a) she was not afraid of being killed.
(b)
she felt that she is entitled to do whatever she liked.
(c)
she did not like walking on the pavement.
(d)
she was confused.
Solution:
The tone of the
reply she gave suggests that she felt that she is entitled to do whatever she
liked.
Option (a) and
(c) cannot be considered as those were not exclusively mentioned and they
cannot be implied.
Coming to option
(d): Actually, it can be understood that, she was not confused but her walking
in the middle of the road had confused the traffic. So option (d) is also
wrong.
Ans: (b)
39. The old lady failed to realize that
(a) she was not really free.
(b)
her liberty was not unlimited.
(c)
she was an old person.
(d)
roads are made for motor vehicles only.
Solution:
Option (c) is
irrelevant.
Option (a) is
not correct as it is an extreme sentence. She is free to do any work but there
are limits in exercizing those works.
Option (d) looks
very particular, but most part of the passage suggests a general sense.
Ans: (b)

questions should be based on the passage only.
Passage
Crude
mineral oil comes out of the earth as a thick brown or black liquid with a
strong smell. It is a complex mixture of many different substances, each with
its own individual qualities. Most o them are combinations of Hydrogen and
Carbon in varying proportions. Such hydrocarbons are also found in other forms
such as Bitumen, Asphalt and natural gas. Mineral oil originates from the carcasses
of tiny animals and plants that live in the sea. Over millions of years, these
dead creatures form large deposits under the sea bed; and ocean currents cover
them with a blanket of sand and silt. As this mineral hardens, it becomes
sedimentary rock and effectively shut out the oxygen, so preventing the
complete decomposition of the marine deposits underneath. The layers of
sedimentary rock become thicker and heavier. Their pressure produces heat,
which transforms the tiny carcasses in to crude oil in a process that is still
going on today.
40. Mineral oil deposits under the sea do not get
completely decomposed because they
(a) are constantly washed by the ocean
currents.
(b)
become rock and prevent oxygen from entering them.
(c)
contain a mixture of hydrogen and carbon.
(d)
are carcasses of organisms lying in saline conditions.
Solution:
”As this mineral
hardens, it becomes sedimentary rock and effectively shut out the oxygen, so
preventing the complete decomposition of the marine deposits underneath.” => as per this quote from the passage, we
can choose option (b)
Ans: (b)
41. Sedimentary rock leads to the formation of oil
deposits because
(a) there are no saline conditions below it.
(b)
it allows some dissolved oxygen to enter the dead organic matter below it.
(c)
weight of overlying sediment layers causes the production of heat.
(d)
it contains the substances that catalyze the chemical reactions required to
change the dead organisms into oil.
Solution:
” The layers of
sedimentary rock become thicker and heavier. Their pressure produces heat,
which transforms the tiny carcasses in to crude oil in a process that is still
going on today.” => as per this quote
from the passage, we can choose option (c)
Ans: (c)

items should be based on the passage only.
Passage
Ecological
research over the last quarter of the century has established the deleterious
effects of habitat fragmentation due to the mining, highways and such other
intrusions on forests. When a large block of forests gets fragmented into
smaller bits, the edges of all these bits come into contact with human
activities resulting in the degradation of the entire forests. Continuity of
forested landscapes and corridors gets disrupted affecting several extinction
prone species of wild life. Habitat fragmentation is therefore considered as
the most serious threat to biodiversity conservation. Ad hoc grants of forest
lands to mining companies coupled with rampant illegal mining is aggravating
this threat.
43. What is the central focus of the passage?
(a) Illegal mining in forests
(b)
Extinction of wild life
(c)
Conservation of nature
(d)
Disruption of habitat
Solution:
The essence of
the passage is:
Due to some
activities like mining, highways etc, there is disruption in landscapes and
corridors. This is affecting several species of wild life.
The central
theme may be “disruption of habitat”
Ans: (d)
44. What is the purpose of maintaining the continuity
of forested landscapes and corridors?
1. Preservation of biodiversity
2. Management of mineral sources
3. Grant of forest lands for
human activities
(a) 1
only
(b)
1 and 2
(c)
2 and 3
(d)
1,2 and 3
Solution:
Option 2 is out
of the scope of the passage. Option 3 has a negative tinge where as the
maintaining of the continuity of forested landscapes and corridors is for a
good purpose. Option 1 only is correct.
Ans: (a)
Passage-3
Malnutrition
most commonly occurs between the ages of six months and two years. This happens
despite the child’s food requirements being less than that of an older child.
Malnutrition is often attributed to poverty, but it has been found that even in
households where adults eat adequate quantities of food, more than fifty
percent of children-under-five do not consume enough food. The child’s
dependence on someone else to feed him/her is primarily responsible for the
malnutrition. Very often the mother is working and the responsibility of
feeding the young child is left to an older sibling. It is therefore crucial to
increase awareness regarding the child’s food needs and how to satisfy them.
45. According to the passage, malnutrition in children
can be reduced
(a)
if the children have regular intakes of food
(b)
after they cross the age of five
(c)
if the food needs of younger children are known
(d)
if the responsibility of feeding younger children is given to adults
Solution:
It is no where
mentioned that malnutrition can be reduced after age of five. So option (b) can
be avoided.
Even if the
children have regular intakes, it may not suffice. The quantity and quality of
food may be more important. Option (a) can be avoided.
No where it is
suggested that the responsibility of younger children shall be given to adults.
So answer option (d) can be avoided.
“It is therefore crucial to increase awareness
regarding the child’s food needs and how to satisfy them” => this sentence
of the passage hints at answer option (c).
Ans: (c)
46. According to the author, poverty is not the main
cause of malnutrition, but the fact that
1. taking care of younger ones
is not a priority for working mothers.
2. awareness of nutritional needs
is not propagated by the public health authorities
Select
the correct answer using the code given below:
(a)
1 only
(b)
2 only
(c)
Both 1 and 2
(d)
Neither 1 nor 2
Solution:
Both the given
options 1 and 2 are extreme and derogatory and are no where hinted in the
passage.
There is no mention about Public Health
authorities in the passage and hence option (2) can be straight away rejected.
It is mentioned
that “Very often the mother is working and the responsibility of feeding the
young child is left to an older sibling” => This does not mean that “taking
care of younger ones is not a priority for working mothers”. In this way it is
an extreme statement and hence option(2) can also be avoided.
Ans: (d)
47. You are the head of your office. There are certain
houses reserved for the allotment to the office staff and you have been given
the direction to do so. A set of rules for the allotment of houses has been
laid down by you and has been made public. Your personal secretary who is very
close to you, comes to you and pleads that as his father is seriously ill, he
should be given priority in allotment of a house. The office secretariat that
examined the request as per the rules turns down the request and recommends the
procedure to be followed according to the rules. You do not want to annoy your
personal secretary. In such circumstances, what would you do?
(a) Call him over to your room and personally explain why the allotment
cannot be done.
(b) Allot the house to him to win his loyalty.
(c) Agree with the office note to show that you are not biased and that
you do not indulge in favouritism.
(d) Keep the file with you and not pass any orders.
Solution:
Option (d) can’t
be selected as it shows indecisiveness.
Option (b) can’t
be selected as it leads to totally against to the rules.
Option(c)
suggests the straight-forward procedure. But as it is mentioned not to annoy
the personal secretary, it is better to personally explain him, why can’t the
allotment be made to him. This little personal attention is not wrong and it
will help to clear the air.
Ans: (a)
48. While travelling in a Delhi-registered commercial
taxi from Delhi to an adjacent city (another state), your taxi driver informs
you that as he has no permit for running the taxi in that city, he will stop at
its transport office and pay the prescribed fee of Rs forty for a day. While
paying the fee at the counter you find that the transport clerk is taking an
extra fifty rupees for which no receipt is being given. You are in a hurry for
your meeting. In such circumstances, what would you do?
(a) Go up to the counter and ask the clerk to give back the money which
he has illegally taken.
(b) Do not interfere at all as this is a matter between the taxi driver
and the tax authorities.
(c) Take note of the incident and subsequently report the matter to the
concerned authorities.
(d) Treat it as a normal affair and simply forget about it.
Solution:
Options (b) and
(d) can’t be selected as it shows irresponsibility on part of a citizen.
Option (a) can’t
be selected as it is mentioned that you are in hurry to attend a meeting and
may not take risk of wasting time as it may lead to an argument etc.
Option(c) is
suitable option.
Ans: (c)
49. A person lives in a far off village which is
almost two hours by bus. The villagers neighbor is a very powerful landlord who
is trying to occupy the poor villager’s land by force. You are the district
magistrate and busy in a meeting called by a local minister. The villager has
come all the way, by bus and by foot, to see you and give an application
seeking protection from the powerful landlord. The villager keeps on waiting
outside the meeting hall for an hour. You come out of the meeting and are
rushing to another meeting. The villager follows you to submit his application.
What would you do?
(a) Tell him to wait for another two hours till you come back from your
next meeting.
(b) Tell him that the matter is actually to be dealt by a junior officer
and that he should give the application to him.
(c) Call one of your senior subordinate officers and ask him to solve the
villager’s problem.
(d) Quickly take the application from him, ask him a few relevant
questions regarding his problem and then proceed to the meeting.
Solution:
Direct interaction with the villager may be
more soothing to him and hence options (b) and (c) are ruled out. Option (a)
can also be avoided as it makes further inconvenience to the villager.
Ans: (d)
50. There is a shortage of sugar in your district
where you are the district Magistrate. The government has ordered that only a
maximum amount of 30 kg sugar is to be released for wedding celebrations. A son
of your close friend is getting married and your friend requests you to release
at least 50 kg sugar for his son’s wedding. He expresses annoyance when you
tell him about the Government’s restrictions on this matter. He feels that since
you are the district magistrate you can release any amount. You do not want to
spoil your friendship with him. In such circumstances how would you deal with
the situation?
(a) Release the extra amount of sugar which your friend has requested for.
(b) Refuse your friend the extra amount and strictly follow the rules.
(c) Show your friend the copy of the Government instructions and then
persuade him to accept the lower amount as prescribed in the rules.
(d) Advise him to directly apply to the allotting authority and inform
him that you do not interfere in this matter.
Solution:
This is similar
to the question on “allotment of houses” (Q.47).
Option (a) is
ruled out as it is against the rules.
Option (b) is a
straight-forward approach but is ruled out as it is a harsh way to deal with as
you do not want to spoil relationship with your friend. Option (d) also looks a
bit harsh and indicates that you are running away from the problem. Option (c) looks more appropriate.
Ans: (c)
51. You are in-charge of implementing the Family
Planning Programme in an area where there is a strong opposition to the present
policy. You want to convince the residents of the need for keeping small
families. What would be the best way of
communicating this message?
(a) By logically explaining to the residents the need for family planning
to improve the health and living standards.
(b) By encouraging late marriages and proper spacing of children.
(c) By offering incentives for adopting family planning devices.
(d) By asking people who have been sterilized or are using contraceptives
to directly talk to the residents.
Solution:
The point here
is to convince the residents for keeping small families. Options (b) and (c)
are not about the methods to convince but rather these are methods for
implementation. Option (d) may be useful as a supporting method but not as a
direct method for convincing.
Option (a) looks
more suitable option.
Ans: (a)
52. You are a teacher in a university and are setting
a question paper on a particular subject. One of your colleagues whose son is
preparing for the examination on that subject, comes to you and informs you
that it is his son’s last chance to pass that examination and whether you could
help him by indicating what questions are going to be in the examination. In
the past your colleague has helped you in another matter. Your colleague
informs you that his son will suffer from depression if he fails in the
examination. In such circumstances, what would you do?
(a) In view of the help he had given you, extend your help to him.
(b) Regret that you cannot be of any help to him.
(c) Explain to your colleague that this would be violating the trust of
the university authorities and you are not in a position to help him.
(d) Report the conduct of your colleague to the higher authorities.
Solution:
Option (a) is
out of question as it is a violation of conduct rules. Option (b) is straight
forward but little rude given the sensitivities involved and hence may be
avoided.
Option (c) looks
more suitable option.
Option (d) is
not the immediate solution given the sensitivities involved. It may be used
only if you are very much compiled to commit a mistake.
Ans: (c)
Passage
Financial
markets in India have acquired greater depth and liquidity over the years.
Steady reforms since 1991 have led to growing linkages and its financial system
with the global economy. Weak global economic prospects and continuing
uncertainties in the international financial markets therefore, have had their
impact on the emerging market economies. Sovereign risk concerns particularly
in the Euro area, affected financial markets for the greater part of the year
with contagion of Greece’s sovereign debt problem spreading to India and other
economies by way of higher-than-normal levels of volatility.
The
funding constraints in international financial markets could impact both the
availability and cost of foreign funding for banks and corporates. Since the
Indian financial system is bank dominated , banks ability to withstand stress
is critical to overall financial stability. Indian banks, however remains
robust, not withstanding a decline in capital to risk weighed assets ratio and
a raise in nonperforming asset levels in the recent past. Capital adequancy
levels remain above the regularity requirements. The financial market
infrastructure continues to function without any major disruption. With further
globalization, consolidation, deregulation and diversification of these
financial systems, the banking business may become more complex and riskier.
Issues like risk and liquidity management and enhancing skill therefore assume
greater significance.
53. According to the passage, the financial markets in
the emerging market economies including India had the adverse impact in recent
years due to
1. Weak global economic prospects
2. Uncertainties in the international
financial markets
3. Sovereign
risk concerns in the Euro area.
4. Bad monsoons and the resultant crop
loss
Select

factors can be taken directly from lines 2 to 5 of 1st paragraph.
Option (4) is out of scope of the para and all other options are mentioned.
Ans: (b)
54. The Indian
financial markets are effected by global changes mainly due to the
(a)
Increased inflow of remittances from abroad
(b)
Enormous increase in the foreign exchange reserves
(c)
Growing global linkages and integration of the Indian financial markets
(d)
Contagion of Greece’s sovereign debt problem
Solution:
This is again a straight forward question.
“Sovereign risk
concerns particularly in the Euro area, affected financial markets for the
greater part of the year with contagion of Greece’s sovereign debt problem
spreading to India and other economies by way of higher-than-normal levels of
volatility”=> this sentence of 1st para hints at answer option
(d)
Ans: (d)
55. According
to the passage, in the Indian financial system, banks ability to withstand
stress is critical to ensure overall financial stability because Indian
financial system is
(a)
controlled by the Government of India
(b)
less integrated with banks
(c)
controlled by Reserve Bank of India
(d)dominated
by banks
Solution:
This is again a
straight forward question.
“Since the
Indian financial system is bank dominated , banks ability to withstand stress
is critical to overall financial stability”=> this sentence of 2nd
para hints at answer option (d)
Ans: (d)
56. Risk and liquidity management assumes more
importance in the Indian banking system in future due to
1. further globalization
2. more consolidation and deregulation of
the financial system
3. further
diversification of the financial system
4. more financial inclusion in the economy
Select
the correct answer using the code given below:
(a)
1, 2 & 3
(b)
2, 3 & 4
(c)
1 & 2 only
(d) 3 & 4 only
Solution:
This is a
straight forward question. The factors can be taken directly from lines 6 to 8
of 2nd paragraph. Option (4) is out of scope of the para and all
other options are mentioned.
Ans: (a)
Passage-4
A
number of empirical studies find that farmers are risk-averse, though only
moderately in many cases. There is also evidence to show that farmers’ risk
aversion results in cropping patterns and input use designed to reduce risk
rather than to maximize income. Farmers adopt a number of strategies to manage
and cope with agricultural risks. These include practices like crop and field
diversification, non-form employment, storage of stocks and strategic migration
of family members. These are also institutions ranging from share tenancy to
kinship, extended family and informal credit agencies. One major obstacle to
risk sharing by farmers is that the same type of risk can affect a large number
of farmers in the region. Empirical studies show that the traditional methods
are not adequate. Hence there is a need for policy interventions, especially
methods that cut across geographical regions.
Policies
may aim at tackling agricultural risks directly or indirectly. Examples of
risk-specific policies are crop insurance, price stabilization and the
development of varieties resistant to pests and diseases. Policies which affect
risk indirectly are irrigation, subsidized credit and access to information. No
single risk specific policy is sufficient to reduce risk and is without side
effects, where as policies not specific to risk influence the general situation
and affect risks only indirectly. Crop
insurance as a policy measure to tackle agricultural risk directly, deserves
careful consideration in the Indian context and in many other developing
countries – because the majority of farmers depend on rain-fed agriculture and
in many areas yield variability is the predominant cause of their income
instability.
57. The need for policy intervention to mitigate risks
in agriculture is because
(a)
farmers are extremely risk averse
(b)farmers
do not know how to mitigate risks
(c)
the methods adopted by farmers and existing risk sharing institutions are not
adequate
(d)majority
of farmers depend on rain-fed agriculture
Solution:
This is a
straight forward question.
“Empirical
studies show that the traditional methods are not adequate. Hence there is a
need for policy interventions, especially methods that cut across geographical
regions”=> these last two lines of 1st para hints at answer
option (c)
Ans: (c)
58. Which of the following observations emerge from
the above passage?
(a)
One can identify a single policy that can reduce risk without any side-effect.
(b)No
single risk-specific policy is sufficient to reduce agricultural risk.
(c)
Policies which affect risk indirectly can eliminate it.
(d)Government’s
policy intervention can mitigate agricultural risk completely.
Solution:
It’s again a straight forward one and the
answer can be directly taken from 4th line of 2nd
paragraph.
Ans: (b)
Passage-1
The law in many parts of the world
increasingly restricts the discharge of agricultural slurry in to water
courses. The simplest and most economically sound practice returns the material
to the land as semisolid manure or as sprayed slurry. This dilutes its concentration in the
environment to what might have occurred in a more primitive and sustainable
type of agriculture and converts pollutant into fertilizer. Soil microorganisms
decompose the organic components of sewage and slurry and most of the mineral
nutrients become available to be absorbed again by the vegetation.
The
excess input of the nutrients, both nitrogen and phosphorus – based, from
agricultural runoff (and human sewage) has caused many ‘healthy’ oligotrophic
lakes (low nutrient concentrations, low plant productivity with abundant water
weeds, and clear water) to change to eutrophic condition where high nutrient
lead to high phytoplankton productivity (sometimes dominated by bloom-forming
toxic species). This makes the water turbid, eliminates large plants and, in
the worst situations, leads to anoxia and fish kills; so called cultural
eutrophication. Thus important ecosystem services are lost, including the
provisioning service of wild-caught fish and cultural service associated with
recreation.
The
process of cultural eutrophication of lakes has been understood for some time.
But only recently did scientists notice huge ‘dead zones’ in the oceans near
river outlets, particularly those draining large catchment areas such as
Mississippi and North America and the Yangtze in China. The nutrient enriched
water flows through streams, rivers and lakes and eventually to the estuary and
ocean where the ecological impact may be huge, killing virtually all
invertebrates and fish in areas up to 70,000 km2 in extent. More than 150 sea areas worldwide
are now regularly starved of oxygen as a result of decomposition of algal
blooms, fuelled particularly by nitrogen from agricultural runoff of
fertilizers and sewage from large cities. Oceanic dead zones are typically
associated with industrialized nations and usually lie off countries that
subsidize their agriculture, encouraging farmers to increase productivity and
use more fertilizer.
59. According to the passage, why should the discharge
agricultural slurry into watercourses be restricted?
1. Losing nutrients in this way is not a
good practice economically.
2. Water courses do not contain the microorganisms that
can decompose organic components of agricultural slurry.
3. The discharge may lead to the eutrophication of water
bodies.
(a) 1 only
(b)
2 and 3 only
(c)
1 and 3 only
(d)
1,2 and 3
Solution:
“The law in many
parts of the world increasingly restricts the discharge of agricultural slurry
in to water courses. The simplest and most economically sound practice returns
the material to the land as semisolid manure or as sprayed slurry”=> These
sentences from 1st paragraph hint that loosing the nutrients in this
way is not a good economical practice. So option (1) can be considered.
Options (2) and
(3) are evident from 2nd paragraph.
Ans: (d)
60. The passage refers to the conversion of “pollutant
to fertilizer”. What is the pollutant and what is the fertilizer in this
context?
(a) Decomposed organic component of slurry is pollutant and
microorganisms in soil constitute fertilizer.
(b)
Discharged agricultural slurry is pollutant and decomposed slurry in soil is
fertilizer
(c)
Sprayed slurry is pollutant and watercourse is fertilizer
(d)
None of the above expressions is correct in this context
Solution:
Option (b) is
easy to select.
Ans: (b)
61. According to the passage, what are the effects of
indiscriminate use of fertilizer?
1. Addition of pollutants to the soil
and water.
2. Destruction of decomposer microorganisms in soil.
3. Nutrient enrichment of water bodies.
4. Creation of algal blooms.
(a) 1 only
(b)
1,3 and 4 only
(c)
2 and 4 only
(d)
1,2,3 and 4
Solution:
Option 2 ie.,
destruction of microorganisms is not mentioned anywhere in the passage whereas
all other options seem to be taken from the passage.
Ans: (b)
62. What is/are the characteristics of a water body
with cultural eutrophication?
1. Loss of ecosystem services.
2. Loss of flora and fauna.
3. Loss of mineral nutrients.
(a) 1 only
(b)
1 and 2 only
(c)
2 and 3 only
(d)
1,2 and 3
Solution:
Options 1 and 2 seem
to be the characteristics of ‘cultural eutrophication‘. Option 1 can be taken
from para-2 and option 2 can be implied from para-3. Option 3 seems odd option
in this context.
Ans: (b)
63. Consider the following diagrams:
x men, working
at constant speed, do a certain job in y days. Which one of these diagrams
shows the relation between x and y?
(a) diagram I
(b)
diagram II
(c)
diagram III
(d)
diagram IV
Solution:
Logical
Explanation:
Diagram I: Even if for zero x, there
exists some y. This means, even if there is no men, there exist some working
days, which is wrong.
Diagram II: If x is increased y is also
increased here. This means if no.of men is increased then the no of working
days increased, which is wrong.
Diagram III: This has two parts in it,
a vertical line and a horizontal line. Vertical line suggests infinite working
days for some number of workers, which is wrong. Horizontal line suggests, same
working days even if the no of men is increased/decreased which is also wrong.
Diagram IV: This depicts the correct
relation. When no.of men increases, then no.of days decreases and vice versa.
Mathematical
Explanation:
Here x and y are
inversely related. If x, the number of men increases, then, y, the number of
days for completing the work decreases => x α (1/y) => xy = constant
=> this is an equation of a rectangular hyperbola. Diagram IV resembles a hyperbola
and hence is the answer.
Ans: (d)
64. A cube has
six numbers marked 1, 2, 3, 4, 5 and 6 on its faces. Three views of the cube
are shown below:
(a)
2 and 3 (b) 6 and 1 (c) 1 and 4 (d) 3 and 1
Solution:
If we check the
first two cubes, the common number 1 has numbers 4,6,2 and 3 on its four
adjacent faces. So the remaining number 5 is on the opposite face of 1. à
(1)
Check the 4th
cube. Here we need to find two adjacent numbers of 5.
Method-I
From
statement(1), in other way, we can say that, 2,3,4 and 6 are the adjacent numbers
of 5. So out of all, answer option (a) has
correct combination.
Method-II
From the statement
(1) itself, we can eliminate three answer options. Number 1 should not be an
adjacent number of 5 because it is the opposite number of 5 (from statement
(1)) . So answer options (b),(c) and (d) can be eliminated as each of these
options have 1 as one of its two numbers.
Ans: (a)

Solution:
From fig-2, we can say that 40% of Physics professors belong to the age
group 35-44. From fig-1, we can find that there are 32 male and 8 female
Physics professors. In total there are 40 Physics professors, out of which 40%
belong to 35-44 age group.
40% 0f 40 = 16
Ans: (b)
66. Which one of the following disciplines has
the highest ratio of males to females?
(a) Physics (b) Mathematics (c) Chemistry (d) Economics
(a) Physics (b) Mathematics (c) Chemistry (d) Economics
Solution:
Check answer options one by one for ratio of
males to females.
Physics: Male:Female = 32:8 = 4:1
Mathematics: Male:Female = 28:8 = 7:2 =
3.5:1
Chemistry: Male:Female = 16:22 < 1
and hence can be eliminated (as it is asked for highest ratio)
Economics: Male:Female = 24:8 = 3:1
Ans: (a)
67. What percentage of all Psychology professors
are females?
(a) 40% (b) 50% (c) 60% (d) 70%
(a) 40% (b) 50% (c) 60% (d) 70%
Solution:
There are 4 male and 6 female Psychology
professors. In total there are 10 Psychology professors.
There are 6
female professors out of all Psychology professors => 6/10 *100 = 60%
Ans: (c)
68. If the number of female Physics professors in
the age group 25 - 34 equals 25% of all the Physics professors in that age
group, then what is the number of male Physics professors in the age group 25 -
34?
(a)9 (b) 6 (c) 3 (d) 2
(a)9 (b) 6 (c) 3 (d) 2
Solution:
From fig-2, we can see that 30% of Physics professors belong to the age
group 25-34. From fig-1, we can find that there are 32 male and 8 female
Physics professors. In total there are 40 Physics professors, out of which 30%
belong to 25-34 age group.
30% of 40 = 12. So there are 12
Physics professors in the age group 25-34 à
(1)
It is given
that, the number of female Physics
professors in the age group 25 - 34 equals 25% of all the Physics professors in
that age group => 25% of 12 = 3 are female professors in that age group à (2)
From (1) and
(2), we can say that 12-3=9 male professors belong to 25-34 age group.
Ans: (a)
69. If the Psychology professors in the
University constitute 2% of all the professors in the University, then what is
the number of professors in the University?
(a) 400 (b) 500 (c) 600 (d) 700
(a) 400 (b) 500 (c) 600 (d) 700
Solution:
From fig-1, we can find that there are 4+6=10 Psychology professors. It
is given that this constitutes 2% of all professors.
If 2% is 10, then what is 100% => 100/2 * 10 = 500
Ans: (b)
sir
ReplyDeletein q no 9 . if we add all in 1 matrix it comes to 110. subsequently in 2 it comes 108 so why cant 7 be the right option as in 3 it will be 106
There is some logic in your argument. But for these type of problems, we need to find a relation between the numbers given in one table. This relation is repetitive for the other tables. But there need not be any relation between two tables. It's not a sequence type of problem. There are three numbers in each table and we need to find the relation between the three numbers in a table such that the same relation can be repeated for three numbers in other table.
DeleteIn the solution of 68, please see the lines once again:
ReplyDeleteIt is given that, the number of female Physics professors in the age group 25 - 34 equals 25% of all the Physics professors in that age group => 25% of 40 = 10 are female professors in that age group à (2)
Here, isn't it all the physics professors in that age group=25% of 12 ?? ( since it says that in that age group 25-34), then the answer becomes 9.
Isn't it ??
Please correct your answer........
ReplyDeleteQ no. 68
number of physics professors in the age group 25 - 34 equals 30% of all the Physics professors so 30 % of 40 is =>12
now as given in the question
number of female Physics professors in the age group 25 - 34 equals 25% of all the Physics professors in that age group (25-34)
so we have to find 25 % of 12 (physics professor 25-34) not 40 (all physics professor)
=>so 25 % of 12 is 3
3 female physics professor are there in age group 25-34
so it concludes that university have
9 male physics professor in age group 25-34
so option (a) is correct option
Thanks for the information, it is corrected now..
Deletethanks u sir

ReplyDeleteQ.no 15..can you plz explain it little bit in words..
ReplyDeleteThen, total payment for car A = 6a+40(a/8)
how comes 40 (a/8)
cost of diesel is 40 per litre.
Deletemileage = distance/number of litres consumed
=> number of litres consumed = distance/mileage
This is (a/8) in case of car A
Hence cost of diesel = 40*(a/8)
I hope it's clear now
Thanks you. Good Blog.
