3x3 =

1x3 =
3 u |
The difference in the age between Gabriel and Michael at first and in the end remains unchanged. Make the difference in the age between Gabriel and Michael the same. LCM of 3 and 1 is 3.
Increase in Gabriel's age
= 6 u - 4 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Michael's age now
= 9 u
= 9 x 3
= 27
Answer(s): 27
