Difference |
Before |
2x1 = 2 u |
5x1 = 5 u |
3x1 = 3 u |
Change |
+ 24 |
+ 24 |
|
After |
2x3 = 6 u |
3x3 = 9 u |
1x3 = 3 u |
The difference in the age between Warren and Warren's cousin remains unchanged. Make the difference in age the same. LCM of 3 and 1 is 3.
Increase in the age of Warren
= 6 u - 2 u
= 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Warren's age now
= 6 u
= 6 x 6
= 36
Answer(s): 36
