You can put this solution on YOUR website! Find three 3 digit numbers using the digits 1-9 only once each
so that the number in row two is twice the number in row one
and the number in row three is three times the number in row one.
There may be additional solutions
:
Let the 3 digit number = x, y, z
:
"the number in row two is twice the number in row one"
y = 2x
:
"the number in row three is three times the number in row one."
z = 3x
:
We know x < 4, try 3
then
y = 2(3) = 6
z = 3(3) = 9
:
The number: 369
:
If x = 2, then 246
:
If x = 1, then 123
