Question

30 men are needed to build a house in 20 days working 8 hrs a day. if the work has to be finished in 15 days working 10hrs a day, how many more men have to be employed

Answer 1

☆Hello friend☆

Number of workers required to build a house i 20 days for 8hrs = 30

Number of workers required to build a wall 1 day and 1 hr = 30 ×8 × 20

Number of worker required to build a wallin 15 day and 10 hr = 30 × 8 ×20 × 1/ 15 × 1/10

= 2 ×8 × 2
= 32

So more workers required = 32 - 30
= 2 workers.

Hope it helps☺!
