Read Solution (Total 1)

881 is NOT the answer to the question posed (or any reasonable variation I can think of right now):

Suppose Raju has 881 coins.
If he gives 1 to the driver (leaving 880),
then gives 1/5 of the remaining (880/5=176) to the first son (leaving 704),
then again gives 1 to the driver, that leaves 703 coins.
He cannot give 1/5 of the remaining to the 2nd son. 703 is not divisible by 5.
(In my country it is illegal to cut up coins, so we will not.)
