Read Solution (Total 1)
-
- 2 days
Work done by father in 3 days = 3*(1/8)=3/8
Remaining work = 1 - 3/8 = 5/8
Let son alone takes 'x' days to finish the work and remaining work is finished in 1 day.
So, 1 day work of father and son = 1/8 + 1/x = 5/8
=> 1/x = 1/2 or x=2
Hence son alone takes 2 days to finish the work. - 6 years agoHelpfull: Yes(2) No(0)
