Verified Answer
Salim can do a piece of work in 30 days and Javed can do the same work...
Given,
Salim’s 1 day’s work = 1/30
Javed’s 1 day’s work = 1/45
If they work together then work will be completed in =
= (1/30) + (1/45)
= 1/18
(Salim + Javed)’s 1 day’s work = 1/18
If they work together then work will be completed in 18 days.
Fraction of work completed in 15 days =
= 15 × (1/18)
= 5/6
Remaining fraction of work after 15 days =
= 1 - (5/6)
= 1/6
Remaining fraction of work after 15 days = 1/6
Salim will complete 1/6th of work in =
= (1/6) × (30)
= 5
∴ Salim will complete remaining work in 5days.
