| Before |
1x1 =
1 u |
4x1 =
4 u |
3x1 =
3 u |
| Change |
+ 32 |
+ 32 |

| After |
3x3 =
9 u |
4x3 =
12 u |
1x3 =
3 u |
The difference in the age between Lee and Lee's cousin remains unchanged. Make the difference in age the same. LCM of 3 and 1 is 3.
Increase in the age of Lee
= 9 u - 1 u
= 8 u
8 u = 32
1 u = 32 ÷ 8 = 4
Lee's age now
= 9 u
= 9 x 4
= 36
Answer(s): 36
