Question

120 men working 9 hours a day can construct a road in 40 days. How long would it take to Construct the same road, if 150 men work 6 hours a day on it? Explain It completely ans. is 48days ​

Answer 1

Answer: they construct the road in 48 days

Step-by-step explanation:

Let, required time = x days

If 120 men working 9hr a day can construct in 40 days = 1 road

Then, 1 man working 1 hr a day can construct in 1 day r 1/(120×9×40) road

So, 150 men working 6 hr a day can construct in 1 day = (150×6) /(120×9×40) road

They construct the road in = (120×9×40)/(150×6) = 48 days
