I am a 3 -digit # divisable by 3-My tens digit is 3 times as great as my hundreds digit and the sum is 15?

Answer 1

The answer is 393.

Start with 333.
It's an easy 3-digit number that is divisible by 3
Tens digit id 3 times more than hundreds.
So 393.
Does it add up to 15?
Yes it does!

Answer 2

Let h= the hundred's digit
Let t = the ten's digit
Let u = the units
Then the number is 100h +10t +u
We are given that t=3h and h+t+u=15
If h=1 then t =3 so u= 11 which is impossible

If h=2 then t=6 so u =7 This would give 267 as the number but
it is not divisible by 3 and so must be rejected

So h=3 and t=9 must be correct because any larger value of h would produce too large a number for t.

Thus u = 15-12=3 and the final solution is 393
