20 women can complete apiece of work in 7 day. If 8 more women are put on the job. In how many days will they complete the work?
-
- 4.5 days
- 5 days
- 5.5 days
- 4.5 days
Correct Option: B
Given, M1 = 20 D1 = 7, M2 = 20 + 8 = 28
and D2 = ?
Using formula, M1D1 = M2D2
⇒ 20 x 7 = 28 x D2
∴ D2 = (20 x 7)/28 = 5 days
