Question

A project manager hired 15 men to complete a project in 40 days. However, after 30 days, he realized that only 1/2 of the work is completed. How many more men does he need to hire to complete the project on time?​

Answer 1

Answer:

30

Step-by-step explanation:

15 men take 30 days to complete x/2 work

(assuming x to be the total work)

so to complete the same amount of work(x/2) in 1/3rd amount of time, we need 3 times the original men=45 men

So extra men needed=45-15=30 men
