The number of female candidates who qualified from state B in 2021 is approximately what percentage of the male candidates who qualified from state A in 2022?

A16
B22 ✓ Correct
C20
D18
Correct answer: (B) 22
Explanation

The figure is about 22%, so the answer is 22.

Female qualifiers from B in 2021 are 142000 times 0.45 times 0.16 times 1 by 4, which is 2556.

Male qualifiers from A in 2022 are 180000 times 0.52 times 0.20 times 28 by 45, which is 11648.

The required percentage is 2556 divided by 11648 times 100.

This works out to about 21.94%.

Rounded, this is about 22%.

Each count uses the correct year's total, qualifying percentage, state share and gender ratio.
