The difference in the age between Neave and his auntie at first and in the end remains the same.
Difference in the age between Neave and his auntie
= 4 u - 1 u
= 3 u
3 u = 36
1 u = 36 ÷ 3 = 12
The increase in age of Neave and his auntie remains the same.
Number of years' time so Neave's auntie will be 4 times as old as Neave
= 12 - 2
= 10
Answer(s): 10
