The difference in the age between Mr Wesley and his niece at first and in the end remains the same.
Difference in the age between Mr Wesley and his niece
= 5 u - 1 u
= 4 u
4 u = 49 - 5
4 u = 44
1 u = 44 ÷ 4 = 11
Number of years' time so Mr Wesley will be 5 times as old as his niece
= 11 - 5
= 6
Answer(s): 6
