City-wise population by males, females and transgenders in five cities A–E (some values are percentages, some are numbers).

City	Males	Females	Transgenders
A	45%	30%	2000
B	50%	3000	35%
C	8000	35%	15%
D	45%	3600	25%
E	38%	32%	4200

The population of City C is what percent less than the population of City B?

A30%

B25%

C20% ✓ Correct

D17.5%

Correct answer: (C) 20%

Explanation

The answer is 20 percent.

In City B the females are 100 minus 50 plus 35, which is 15 percent, and this equals 3000, so the total is 20000.

In City C the males are 100 minus 35 plus 15, which is 50 percent, and this equals 8000, so the total is 16000.

So City C is 20000 minus 16000, which is 4000 less than City B.

As a percentage this is 4000 divided by 20000, times 100.

That is 20 percent.

So the answer is 20 percent.
