| Before |
8x1 =
8 u |
3x1 =
3 u |
5x1 =
5 u |
| Change |
+ 14 |
+ 14 |

| After |
2x5 =
10 u |
1x5 =
5 u |
1x5 =
5 u |
The difference in the age of Mr Michael and Warren at first and in the end remains unchanged. Make the difference in age the same. LCM of 5 and 1 is 5.
The increase in the age of Mr Michael and Warren is the same.
Increase in Warren's age
= 5 u - 3 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Warren's current age
= 5 u
= 5 x 7
= 35
Answer(s): 35
