Hi Let me assume that your Question is,
5 men or 8 women do equal amount of work in a day. a job requires 3 men and 5 women to finish the job in 10 days how many woman are required to finish the job in 14 days.
Then the step by step solution is
1 man can do the work of 8/5 = 1.6 women
Equivalent of (3*1.6 + 5 = 9.8) women take 10 days
