Kudos for correct solution.

6² = 36

So, the question is asking "Which of the following is a multiple of 36?"

First off, 36 is EVEN, which means all multiples of 36 are EVEN.

A and B are ODD numbers, so ELIMINATE A and B

Second, 36 is a multiple of 9, which means all multiples of 36 are also multiples of 9.

In other words, the

correct answer must be divisible by 9If a number is divisible by 9, the sum of its digits must be divisible by 9Check the remaining answer choices...

(C) 52,224

5+2+2+2+4 = 15

15 is NOT divisible by 9, which means 52,224 is NOT divisible by 9

ELIMINATE C

(D) 89,892

8+9+8+9+2 = 36

36 IS divisible by 9, which means 89,892 IS divisible by 9

KEEP D

(E) 92,044

9+2+0+4+4 = 19

19 is NOT divisible by 9, which means 92,044 is NOT divisible by 9

ELIMINATE E

Answer: D

Cheers,

Brent
