Question

A contractor undertakes to dig a canal, 6 kilometres long, in 35 days and employed 90 men. He finds that after 20 days only 2 km of canal have been completed. How many more men must be employed to finish the work in time ?

Answer 1

Answer:

150 more man

Step-by-step explanation:

Total time given =35 days.

To dig a canal of 2 km in 20 days, 90 men were required.

So, to dig a canal of 1 km in 1 day, 290×20 men will be required.

So, to dig a canal of 4 km in 15 days 15900×4 =240 men will be required.

As 90 men were already employed, so 150 more men are required.
