Using all of the digits from 1 to 9 once each, create three 3-digit numbers that are in ratio of 1: 2: 3. There are four solutions.

Question

please someone solve thia question and tell how to solve 

Answer 1

I read this problem as the three 3-digit number values were in a ratio of 1:2:3, not the digits in each 3-digit number.

Here is one solution!

219  438   657  

Answer 2

No solution, just "higher order thinking".

First one should be obvious

123

Now any multiple is in the same ratio

246

369

That's all. Do not know how to get the fourth. (5, 7, and 8 just do not work!)
