Question

6 men or 10 women can complete a job
in 15 days. In how many days will the
same job be completed by 7 men and
5 women ?​

Answer 1

Step-by-step explanation:

let the efficiency of men be M

and efficiency of women ne W

6M×15= 10W×15

M/W= 10/6

M/W= 5/3

now,

6M×15= (7M+5W)x

6×5×15=(7×5+5×3)x

450= (35+15)x

450= 50x

9=x

7 men and 5 women can do it in 9 days
