**MathMate**, Monday, May 9, 2011 at 6:38pmWe know that the number is divisible by three if the sum of its digits is 15!

It's got 3 digits. When reversed, it is divisible by 6, which means that the reversed number is divisible by 2. This translates to

"the hundred's digit is even".

From

"my tens digit is 3 times as great as my hundreds digit"

we deduce that the number must be one of the three possibilities:

A. 13X

B. 26X

C. 39X

Where X can be found from the fact that the digits add up to 15.

Both A and C will not work because the hundreds digit is not even.

So can you find the number now?
