The difference in the age between Mrs Ee and her daughter remains unchanged.
Difference in their age at first
= 50 - 6
= 44
Difference in their age in the end
= 5 u - 1 u
= 4 u
4 u = 44
1 u = 44 ÷ 4 = 11
Number of years time that Mrs Ee will be five times as old as her daughter
= 1 u - 6
= 11 - 6
= 5
Answer(s): 5
