A. 8
B. 10
C. 15
D. 16

Let the marks of each question be 10
Total marks got by the candidate = 8 x 5 =40 marks

Candidates in a competitive examination consisted of 60% men and 40% women 70% men and 75% women cleared the qualifying test and entered the final test where 80% men and 70% women were successful? Which of the following statements is correct?

A. Success rate is higher for women
B. Overall success rate is below 50%
C. More men cleared the examination than women
D. Both ‘A’ and ‘B’
Explanation:
Let there are 100 persons in which 60 men and 40 women number of men who cleared the qualifying test
= 70 x 60/100 = 42
Number of women who cleared the qualifying test
= 40 x ¾ = 30
Number of men who get success in final test
= 42 x 4/5 = 33.6
Number of women who get success in final test
= 30 x 70/100 = 21
Hence more men cleared the examination than a woman.

10 % of the electorate did not cast their votes in an election between two candidates. 10 % of the votes polled were found invalid. The successful candidate got 54 % of the valid votes and won by a majority of 1620 votes. The number of voters enrolled on the voter’s list was___________?

A. 25000
B. 33000
C. 35000
D. 40000
Explanation:
Let the number of votes enrolled be x
Votes cast = (90/100 × x) = 9x/10
Valid votes = 90% of 9x/10 = (90/100 × 9x/10) = 81x/100
Votes polled by successful candidate
= (54/100 × 81x/100) = 4374x/10000
Votes polled by defeated candidate
= (46/100 × 81x/100) = 3726x/10000
=> 4374x – 3726x = 16200000
=> x = 16200000/648 = 25000

A. 10000
B. 16400
C. 16800
D. 18000
Explanation:
Let the enrolled votes be x,
Votes cast = (75/100 × x) = 3x/4
Valid votes = (98/100 × 3x/4)
= 147x/200 75/100 × 147x/200 = 9261
=> 441x = (9261 × 800)
=> x = 16800
