The difference in the age between Mr Asher and his cousin at first and in the end remains the same.
Difference in the age between Mr Asher and his cousin
= 5 u - 1 u
= 4 u
4 u = 28 - 4
4 u = 24
1 u = 24 ÷ 4 = 6
Number of years' time so Mr Asher will be 5 times as old as his cousin
= 6 - 4
= 2
Answer(s): 2
