If 70 men can finish a piece of work in 48 days, how many men will be needed to finish it in 12 days?

Work = rate x time

One Man can finish ’M' units of work in one day.

70 men worked for 48 days.

Work done = 70 x 48

The same work is done in 12 days.

Work done = M x 12

M x12 = 70 x 48

M = (70 x 48)÷ 12

M= 280

280 Men required to finish it in 12 days.

Ans : 280 men.

Answer 2

70 men can finish a work in 48 days

Let the men needed to finish the work in 12 days be x.

men :- 70 x

days:- 48 12

70×12= 48×x

70×12÷48= x

x = 280
