The number of male candidates who qualified from state E in 2022 is approximately what percentage more than the number of male candidates who qualified from state F in 2021?

A72
B74 ✓ Correct
C70
D76
Correct answer: (B) 74
Explanation

The excess is about 74%, so the answer is 74.

Total qualified in 2022 is 52% of 180000, and state E is 22% of that, then males are 15 parts of 24.

So male qualifiers from E in 2022 are 180000 times 0.52 times 0.22 times 15 by 24, which is 12870.

Total qualified in 2021 is 45% of 142000, and state F is 13% of that, then males are 8 parts of 9.

So male qualifiers from F in 2021 are 142000 times 0.45 times 0.13 times 8 by 9, which is 7384.

The excess is 12870 minus 7384, which is 5486.

The percentage more is 5486 divided by 7384 times 100, about 74%.
