Question

A small–scale company undertakes an agreement to make 540 motor pumps in 150 days and employs 40 men for the work. After 75 days, the company could make only 180 motor pumps. How many more men should the company employ so that the work is completed on time as per the agreement?

Answer 1

40 more workers are needed.

In the first phase of the work ;

Produced pumps = 180

Days = 75

Worker = 40

Remaining pumps = 540-180 = 360

Remaining days = 150-75 = 75

So,

In 75 days 180 pumps are made by = 40 workers

In 75 days 1 pump is made by = 40/180 workers

In 75 days 360 pumps are made by = (40×360)/180 = 80 workers

So, more workers needed = 80-40 = 40 (answer)
