30% of what number is 60? A:180 B:220 C:200 D:150

The answer would be c

C: 200

Step-by-step explanation:

To make this easier, let's start downscale our numbers to 10%, so let's rewrite the question as:

10% of what number is 20?

From there, we can take 10% of each answer

A: 18

B: 22

C: 20

D: 15

C is the only one that ends up being 20, so if we were to multiply each back up to 30% (aka multiplying each answer by 3) we would get:

A: 54

B: 66

C: 60

D: 45

C Matches our answer, so C: 200 is correct.
