The number of more employees needed is 40.
•Given data :
Total pump to make = 540
Total time for the agreement = 150 days
40 men made 180 pumps in 75 days
• So,the remaining number of pumps to make = (540-180) = 360 pumps
• Remaining number of days for the agreement = (150-75) = 75 days
• Now,
In 75 days 180 pumps are made by = 40 men
In 75 days 1 pump is made by = 40/180 men ( direct proportion)
In 75 days 360 pumps are made by = 40×360/180 = 80 men (direct proportion)
• The amount of more men
= Necessary men - Current men
= 80 - 40
= 40
The company needs 40 more men to finish the agreement in the given time. (Answer)
