A.
35
B.
40
C.

D.

Your Answer: Option (Not Answered)

Correct 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.

Length = 480 m and Breadth = 320 m.

Area = (480 x 320) m2 = 153600 m2.
