The difference in the age between Glen and his mother at first and in the end remains the same.
Difference in the age between Glen and his mother
= 5 u - 1 u
= 4 u
4 u = 32
1 u = 32 ÷ 4 = 8
The increase in age of Glen and his mother remains the same.
Number of years' time so Glen's mother will be 5 times as old as Glen
= 8 - 3
= 5
Answer(s): 5
