a man agrees to build a wall 132 ft long in 36days and employees16men.after 20 days he find that only 60ft of wall is finished.how many more men all how working 6 as many hrs,will be require that the work might be finished in time?

Answer 1

in 20 days, only 60/132 = 15/33 of the wall is done. So, that means each man has done 15/528 of the job.

So, 18/33 remains.

At this point, I get confused. What does

working 6 as many hrs

mean? Surely they cannot be working 6 times as many hours.

Anyway, see what you can do with the info so far.
