24 men works for 14 days, 2 days after they started working, 4 more men joined them and after 2 more days, 6 men left. How many more days will they now take to complete the remaining work?

Answer 1

So, the total man-days worked in the 14 days is

2*24 + 2*28 + 10*22 = 324

Without knowing how much total work is needed, there's no way to tell how many more days it will take.
