John said “I have attempted 95% of
the questions correctly in the examination”. What might be the minimum possible
number of questions given in the examination?

(1)19 (2)10 (3)20 (4)100 (5)95

Solution follows here:
95% = 95/100 = 19/20

19/20 is the simplest fraction which can be derived from 95%.

Hence, at the minimum John has answered 19 Q’s correctly out
of the given

**20 Q’s**.**Answer (3)**
Answer=(3)20

ReplyDelete95% of 20 = 19

5% of 20 = 1

So, Min no of questions = 19+1 = 20

yes TSK, your are right, other way of approach for this is:

ReplyDelete95% = 95/100 = 19/20

=> this is the simplified fraction

=> he got 19 correct out of given 20 Q's

=> 20 is the answer
