4 men and 6 women finish a job in 8 days while 3 men and 7 women finish it in 10 days .10 women working throught will finish it in

Answer 1

we can make linear equation,

let work done by one man is x

and work done by 1 woman is y

then ,

4x+6y=8 ... ×3

3x+7y=10 .....×4

12x+18y=24

(- )12x+(-)28y=(-)40

-10y=-20

10 y=20 Ans.
