2x1 =
2 u |

| After |
3x2 =
6 u |
4x2 =
8 u |
1x2 =
2 u |
The difference in the age between Brandon and Brandon's cousin remains unchanged. Make the difference in age the same. LCM of 2 and 1 is 2.
Increase in the age of Brandon
= 6 u - 3 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Brandon's age now
= 3 u
= 3 x 4
= 12
Answer(s): 12
