The difference in the age between Owen and his uncle at first and in the end remains the same.
Difference in the age between Owen and his uncle
= 4 u - 1 u
= 3 u
3 u = 42
1 u = 42 ÷ 3 = 14
The increase in age of Owen and his uncle remains the same.
Number of years' time so Owen's uncle will be 4 times as old as Owen
= 14 - 6
= 8
Answer(s): 8
