Answer 2

It would take 32 days to construct the same road if 150 men work 9 hours a day on it

Step-by-step explanation:

Time taken by 120 men working 9 hours a day to construct road = 40 days

Time taken by 1 man working 9 hours a day to construct road = $40 \times 120$

Time taken by 150 men working 9 hours a day to construct road =$\frac{40 \times 120}{150} =32$

Hence It would take 32 days to construct the same road if 150 men work 9 hours a day on it
