Question

Mohit can complete a work in 50 days, whereas Anuj can complete the same work in 40 days. Find:
(i) work done by Mohit in 20 days.
(ii) work left after Mohit has worked on it for 20 days.
(iii) time taken by Anuj to complete the remaining work.

Answer 1

Mohit can complete a work in 50 days

and Anuj can complete the same work in 40 days

∴ Mohit's one day's work = `1/50`

and Anuj's one day's work =`1/40`

(i) Mohit's 20 day's work = `1/50 xx 20 = 2/5`

(ii) Work left = `1 - 2/5 = (5 - 2)/5 = 3/5`

Anuj can do `3/5` work in = `40xx3/5` days = 24 days
