Answer 1

heya

Let 1 man's 1 day work = x 
and 1 woman's 1 days work = y. 
Then, 4x + 6y = 1/8 
and 3x+7y = 1/10 
solving, we get y = 1/400 [means work done by a woman in 1 day]

10 women 1 day work = 10/400 = 1/40 

10 women will finish the work in 40 days

Answer: Option B

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.
