25 men and 15 women can complete a piece of work in 12 days. All of them start working together and after working for 8 days the women stopped working. 25 men complete the remaining work in 6 days. how many days will it take for completing the entire job if only 15 women are put on the job?

60 days
88 days
94 days
None of these

Correct Answer: None of these

Explanation:

25 men and 15 women can complete, a piece of work in 12 days.
∴ Work done by them in 8 days = 8/12 = 2/3
Remaining work is completed by 25 men in 6 days
∴ Time taken by 25 men to complete the whole work = 3 x 6 = 18 days
From the question
Time taken by 15 women to complete the whole work = 1 / (1/12 - 1/18)
= 1 / {(3 - 2) / 36} = 36/(3 - 2) = 36 days
