I am a 3digit number divisible by three my tens digit is three 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 three

Since tens digit is three times as great as hundreds digit, the hundreds digit must be 1, 2 or 3. If the sum of the digits = 15, this omits the 1 (13?). This leaves 267 and 393. Which fits the other qualities?
