Answer:
number = 267
Explanation:
i am a 3 digit number divisible by 3.
100a + 10b + c
my tens digit is 3 times as great as my hundreds digit
b = 3a, from this we know a = 1, 2, 3, then b = 3, 6, 9
and the sum of my digits is 15.
a + b + c = 15
if you reverse my digits i am divisible by 6 and 3
100c + 10b + a
this is a logic problem, an equation won't help us here
From the given information b = 3a, and the sum of the 3 digits = 15, we have:
1 3 ___; three single digits can't add up to 15
2 6 _7_; this has to be the number
3 9 _3_; reverse number is not different
Check for division by 3 and 6
267/3 = 89
762/6 = 127
267 is the number
