प्रश्न

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.

योग

उत्तर

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

How much time will they take to go 85 km?


In one trip the logboat brings about 20 kg of fish. But other types of boats bring a bigger catch as given in the table. The table also shows the speed of each type of boat, which is how far each boat goes in one hour. Look at the table and calculate -
