The difference in the age between Mr Asher and his niece at first and in the end remains the same.
Difference in the age between Mr Asher and his niece
= 4 u - 1 u
= 3 u
3 u = 50 - 2
3 u = 48
1 u = 48 ÷ 3 = 16
Number of years' time so Mr Asher will be 4 times as old as his niece
= 16 - 2
= 14
Answer(s): 14
