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.
Solution
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
