| Before |
1x2 =
2 u |
4x2 =
8 u |
3x2 =
6 u |
| Change |

| After |
3x3 =
9 u |
5x3 =
15 u |
2x3 =
6 u |
The difference in the age between Gabriel and Gabriel's brother remains unchanged. Make the difference in age the same. LCM of 3 and 2 is 6.
Increase in the age of Gabriel
= 9 u - 2 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Gabriel's age now
= 2 u
= 2 x 4
= 8
Answer(s): 8
