Answer:

B) 8 and 24.

Explanation:

Just by looking at the answer choices, since one number must be three times the other, we can determine that the correct answer is B.

Regardless, let's work this out mathematically. Let the first number be a and the second number be b.

Their difference is 16. Hence:


a-b=16

The first number is three times the second number. So:


a=3b

Substitute:


3b-b=16

Solve for b. Subtract:


2b=16

And divide both sides by two:


b=8

So, the second number is 8.

And since the first number is three times the second, the first number is 24.

Our answer is B as expected.
