a) 30 days b) 35 days c) d) 45 days 40 days​

Answer 1

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 =1/8

and 3x + 7y =1/10

Solving the two equations, we get:

x =11/400

y =1/400

1 woman's 1 day's work =1/400

10 women's 1 day's work =(1/400×10)=1/40

Hence, 10 women will complete the work in 40 days. Please Follow
