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