1. 8 males and 6 females can do a piece of work in 5 days, 5 males and 6 females can complete the same work in 7 days . How many days will a female take to do the job, if she works alone?
- A. 135 days
- B. 135 days
- C. 135 days
- D. 135 days
Answer: Option D
Explanation:
(8M + 6F) × 5 = (5M + 6F) × 7
= > 40M + 30F = 35M + 42F
= > 5M = 12F
Now, (5M + 6F) = 12F + 6F = 18F
18F can do in = 7 days
1F can do in = 18x 7 = 126 days Ans.
