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
