I am a 3 digit number divisible by 3. My tens digit is 3 times as great as my hundreds digit, and the sum of my digits is 15. If you reverse my digits, I am divisible by 6, as well as by 3.

What number am I?

Thank you for your help.

If the hundreds digit is is 1, the tens must be 3, likewise 2 and 6, 3 and 9.

To get 15, the possibilities exclude 1 and 3, because the ones digit cannot be a single digit.

The remaining possibilities are 267 and 393.

Which one fits all the requirements?

I hope this helps.
