Answer: (2) 8 days
Explanation:-
40 men can do complete the work = 18
40 men can do work in a day = 1/18
1 man can do work in a day = 1/18 x 40 = 1/720

40 men can work in 8 days = 1 x 8/18 = 4/9
Remaining work = 1 – 4/9 = 5/9
10 more men joined then number of men = 40 + 10 = 50
50 men can complete the remaining work = 9/5(50/720
= 8 days
Thus, 50 men can complete the remaining the in 8 days.
Hence, the answer is (2) 8 days
