Question

4 men and 6 Women can complete a work in 8 days while 3 men and 7 women can complete it in 10 days .In how many days wil 10 women complete it?​

Answer 1

Answer:

10 women can do it in 30 days

Answer 2

Answer:

40

Step-by-step explanation:

4 men and 6 women 1 day work = 1/8 equation 1

3 men and 7 women 1 day work = 1/10 equation 2

On subtracting above two equations, we get,

1M- 1W = 1/8 - 1/10

= 1/40

So, 1 Women work = 1W = 1M - 1/40 equation 3

Substitute 1W in eqation 1. We will get,

4M + 6(1M - 1/40) = 1/8

on solving, we get, 1M = 11/400

Now substitute 1M in equation 3

1W = 11/400 - 1/40 = 1/400

So, 10 women's 1 day work = 10/400 = 1/40

Therefore, 10 women will complete work in 40 days.
