Question

if 12 men working at 6 hours per day can do a piece of work in 14 days. how many workers can complete the same work in 3 days working 7 hours per day

Answer 1

Step-by-step explanation:

When more than one man/machine work on a particular work or project, the rate of work is calculated as the strength of workers working in a particular time.

So amount of work = men*days*hours.

Since here work is constant,

M 1 X D 1 X H 1 = M 2 X D 2 X H 2

12 X 14 X 6 = M 2 X 8 X 7

M 2 = 18.

Hence 18 men can complete the same work iñ 8 days, working at 7 hours per day.
