Ram decided to plough a farmland in 40 days. He employed 60 men in the beginning and 30 more after 30 days and completed the construction in right time. If he had not employed the additional men, how many days behind schedule would it have been finished? Correct Answer 5 days
Given that, 60 men employed for 30 days and 30 more men employed for next 10 days so that the work could be finished in 40 days.
Let work done by 1 man be 1 unit/day
Thus, the total work = 60 × 30 + (60 + 30) × 10 = 2700 units
Suppose, it takes X days to the finish the whole work, if additional men were not employed.
So, 60 × X = 2700
X = 45 days
Therefore, it takes 5 days more than stipulated time.
