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
