Question

men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 9 days. In how many days will 24 women complete it​

Answer 1

Answer:

let work done by 1 men in 1 day=m

let work done by 1 women in 1 day=w

So,

4m+6w=1/8 .....(1)

3m+7w=1/10 ....(2)

Multiply equation(1) by 3 and equation(2) by 4

12m+18w=3/8

12m+28w=4/10

Subtract the two equations,

10w=

10

4

−

8

3

10w=

80

32−30

10w=

40

So, 10 womens 1 day work will be 1/40

Thus, 10 womens will complete the work in 40 days
