MNC company employed 25 men to do the official work in 32 days. After 16 days, it employed 5 more men and work was finished one day earlier. If it had not employed additional men, it would have been behind by how many days?

Question

Just want to know
At the end how
Delayed time=18-16=2 days
How it happens

Answer 1

projected work was ... 25 men * 32 days = 800 man days

actual work was ... (25 m * 16 d) + [30 m * (32 - 16 - 1) d] = 850 md

the actual work took 50 md more than projected
.. this would have been 2 extra days with the 25 man crew

Answer 2

Very good
