Question

4 men and 6 woman can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it?

Answer 1

Answer:

40

Step-by-step explanation:

Let 1 man's 1 day's work = x and 1 woman's 1 day's work = y.

Then, 4x + 6y = 1 and 3x + 7y = 1 .

8 10

Solving the two equations, we get: x = 11 , y = 1

400 400

1 woman's 1 day's work = 1 .

400

10 women's 1 day's work = 1 x 10 = 1 .

400 40

Hence, 10 women will complete the work in 40 days
