The difference in the age between Wesley and his mother at first and in the end remains the same.
Difference in the age between Wesley and his mother
= 4 u - 1 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
The increase in age of Wesley and his mother remains the same.
Number of years' time so Wesley's mother will be 4 times as old as Wesley
= 9 - 2
= 7
