The difference in the age between Asher and his mother at first and in the end remains the same.
Difference in the age between Asher and his mother
= 3 u - 1 u
= 2 u
2 u = 28
1 u = 28 ÷ 2 = 14
The increase in age of Asher and his mother remains the same.
Number of years' time so Asher's mother will be 3 times as old as Asher
= 14 - 6
= 8
Answer(s): 8
