Question

If 12 workers can build a wall in 48 hours, how many workers will be required to do the same work in 32 hours?

Answer 1

Step-by-step explanation:

The fraction of work done each hour by one worker is 1/15 x 1/48 = 1/720.

In 30 hours one worker could do 30 x 1/720 = 1/24 of the work, so you will need 24 workers to do the work in 30 hours.

Answer 2

Answer:

12 workers =48 hours

work done by each worker in an hour =1/12×1/48=1/576

in 32 hours one worker does=32×1/576=1/18

so 18 workers would be required to do it in 32 hours

why build the wall again ...when it's already built lmao XD!
