If 2 of the men fell sick after the 4th day, how many days would it have taken to complete the house.
:
From the information given, we know that it takes; 5*13 = 65 man-days to complete the house
:
Let d = no. of additional days if 2 fell sick after the 4th day
:
5*4 + 3d = 65
20 + 3d = 65
3d = 65 - 20
3d = 45
d = 15 additional days
hence
4 + 15 = 19 days to complete the house
