Question

10 boys can dig a pitch in 12 hours. How long will 8 boys take to do it​

Answer 1

Answer:

It is given that

1 boys can dig a pitch in 12 hours

We know that the time taken by one boy = 10 (12) = 120 hours

So the time taken by 8 boys to dig the pitch = 120/8 = 15 hours

Hence, 8 boys will take 15 hours to dig the pitch.
