Answer:
48 days
Explanation:
From the given information:
The total number of hours it took 120 men to work for 40 days is:
= 9 × 40
= 360 hours
Now; a single man will have to work for:
= 360 × 120 hours
= 43200 hours
However, for 150 men, the number of hours they will need to work will be:
= 43200 hours/150
= 288 hours
Provided it will take them 6 hours in a day to work;
Then, the number of days required to construct the same road is:
= 288/6
= 48 days
