Question

A piece of work can be done by 24 men in 4 days working 10 hours a day, how many men are needed to complete another work which is twice as large as first one in 48 days working 8 hours a day?

Answer 1

Answer:

5 days

Step-by-step explanation:

If 1 man works 8 hours a day, then he can complete the job in:

1 man = 12 * 5 = 60 days * 8 hours = 480 work hours

But if it’s 10 hours and 5 days and we also need to find the number of men that can actually complete the job so:

The number of total hours in 5 days: 10 * 5 = 50 hours

Therefore the number of men that would be needed to complete the job in 5 days with a rate of 10 hours is:

480/50 = 9.6 or 10 men(rounded)

Let’s check if it’s correct:

9.6 men = 9.6 * 5 = 48 = 9.6 / 48 = 5 days
