Question

If 25 men working 8 hours a day do a job in 63 days how long's would 45 men take to finish the job working 7 hours a day

Answer 1

Answer:

40

Step-by-step explanation:

M1* D1 *T1= M2*D2 *T2

25*8*63= 45*7*X

X= 40

Answer 2

25 men working 8 hours a day = 200 hours of work done a day.

They do a job in 63 days so total time taken is 12,600 hours.

45 men working 7 hours a day = 315 hours of work a day.

Number of days taken = 12,600/315=40
