Question

39 persons can repair a road in 12 days, working 5 hours a day. In how many days will 30 persons, working 6 hours a day, complete the work?

Answer 1

Hey mate! here's your answer,

Let's the work = x

then time taken

$12 \times 5 \times 39 = 2340$

Then in this days taken are 39 persons are 12 they worked 5 hours each everyday.

If same the same done by 30 persons for 6 hours each day then,

let's taken days as - y

then

$y \times 6 \times 30 = 2340 \\ y \times 180 = 2340 \\ y = \frac{2340}{180} \\ y = 13$

therefore y - 13 so they have to work 13 days.

Hope this will help you.
