Question

12 men work 8 hours per day to complete the work in 10 days. To complete the same work in 8 days, working 15 hours a day, the number of men required

Answer 1

Answer:

8 men

Step-by-step explanation:

number of men to complete a work in 10 days, working 8 hours per day = 12

number of men to complete a work in 10 days, working 1 hour per day = 12×8

number of men to complete a work in 1 day, working 1 hour per day = 12×8×10

number of men to complete a work in 8 days, working 1 hours per day = (12×8×10)/8

number of men to complete a work in 8 days, working 15 hours per day

= (12×8×10)/(8×15)

= 8 men
