Question

A bridge can be constructed by 1800 workers in 50 days. How many more such workers should be
employed to complete the work in 30 days?
:11​

Answer 1

Step-by-step explanation:

If 1500 people do the work in 60 days, then one man can do it in 1500*60 days. Therefore 40 men can do it in 1500*60/40=2250. Thus we would need 2250–1500=750 more people to compete the job in 40 days
