The difference in the age between Vaidev and his uncle at first and in the end remains the same.
Difference in the age between Vaidev and his uncle
= 6 u - 1 u
= 5 u
5 u = 35
1 u = 35 ÷ 5 = 7
The increase in age of Vaidev and his uncle remains the same.
Number of years' time so Vaidev's uncle will be 6 times as old as Vaidev
= 7 - 2
= 5
