The difference in the age between Liam and his auntie at first and in the end remains the same.
Difference in the age between Liam and his auntie
= 4 u - 1 u
= 3 u
3 u = 48
1 u = 48 ÷ 3 = 16
The increase in age of Liam and his auntie remains the same.
Number of years' time so Liam's auntie will be 4 times as old as Liam
= 16 - 2
= 14
Answer(s): 14
