Verified Answer
If 2 men and 3 women can do a piece of work in 8 days and 3 men and 2...
|2 x 8 - 3 x 7| men’s work = |3x 8 - 2 x 7| women’s work.
∴ 5 men’s work = 10 women’s work
∴ 1 men’s work = 2 women’s work
2 men’s work = 4 women’s work
∴ Days taken by 5 men + 4 women = 14 women are = 7×8/14 = 4 days
Alternate method-
⇒ (2 M + 3W) 8 = (3M + 2W)7
⇒ 16M + 24W = 21M + 14 W
⇒ 10W = 5M
⇒ 2W = M
⇒ 14W × (x) = 7W × 8
= (x) = 4 days
