3 digit number = XYZ

x=hundreds

Y=tens

Z=ones

"divisible by 3"

(X+Y+Z)/3 = whole number

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

Y=3X

therefore,(X+3X+Z)/3 = whole number

"the sum of my digits is 15"

X+Y+Z=15 or X+3X+Z=15 (from substitution of Y=3X) or Z=15-4X

"if you reverse my digits i am divisible by 6"

ZYX

which means it's divisible by 2!

X = 0, 2, 4, 6, or 8

plug X into here:

(X+3X+Z)/3 = whole number

Z=15-4X

see which ones work!
