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

Find the ratio of the transgender population of City C to the transgender population of City D.

A4:5 ✓ Correct

B5:4

C3:5

D2:5

Correct answer: (A) 4:5

Explanation

The answer is 4 to 5.

In City C the total is 16000, so the transgenders at 15 percent are 2400.

In City D the total is 12000, so the transgenders at 25 percent are 3000.

So the ratio is 2400 to 3000.

Dividing both by 600 gives 4 to 5.

So the transgender ratio of C to D is 4 to 5.

So the answer is 4 to 5.
