12 labourers working 4 hours a day can finish a work in 15 days. If the labourers work 8 hours a day, then how many labourers are required to finish the same piece of work in 9 days?

12 labourers working 4 hours a day can finish a work in 15 days. If the labourers work 8 hours a day, then how many labourers are required to finish the same piece of work in 9 days? Correct Answer 10

 

Let, 1 labourer do 1 unit work per day.

Then, total work = 12 × 4 × 15 = 720 units

Now, total hours = 8

Total days = 9

Numbers of labourers required = N

Then,

N × 8 × 9 = 720

⇒ N = 10

Hence, option 1) is correct.
