Question

96 men were engaged for a project of constructing a railway track of
the length of 18 km in four weeks. After one week it was observed that the work of
4m was completed. How many additional men should be engaged for timely
completion of the project?

Answer 1

Answer:

16 men

Step-by-step explanation:

Work completed by 96 men in 1 week=4km

Work completed by 96 men in 4 weeks=16km

Remaining work= 2km

Number of men required to complete 2 km of work in 1 week =48 (As 96 men for 4km)

But we have 3 weeks for completion of work (Since additional men join after 1 week of starting [4-1=3])

Therefore, no of men=48/3=16  men [if they work for 3 weeks they will complete the 2 km remaining work].

hope this helps you!!
