The difference in the age between Asher and his uncle at first and in the end remains the same.
Difference in the age between Asher and his uncle
= 3 u - 1 u
= 2 u
2 u = 34
1 u = 34 ÷ 2 = 17
The increase in age of Asher and his uncle remains the same.
Number of years' time so Asher's uncle will be 3 times as old as Asher
= 17 - 6
= 11
Answer(s): 11
