Twelve men and six women together can complete a piece of work in four days. The work done by a women in one day is half the work done by a man in one day. If 12 men and six women started working and after two days, six men left and six women joined, then in hoe many more days will the work be completed?	Choose the correct answer.
A) 2 (1/8) days	B) 2 (1/6) days	C) 3 (1/2) days	D) 2 (1/2) days	E) 2 (5/2) days
Work done by a women in one day = 1/2 (work done by a man/day)   One women's capacity = 1/2(one man's capacity)   One man = 2 women.   12 men = 24 women.   12 men + 6 women = 30 women   30 women can complete the work in four days. In the first 2 days they can complete 1/2 of the work. Remaining part of the work = 1/2. If 6 men leave and 6 new women join, then new work force = 30 women - 12 women + 6 women = 24 women.   Time taken by them to complete the remaining work = 1/2 (Time taken by 24 women to complete the work) = 1/2 * (30 * 4)/24 = 2 (1/2) days.   Answer: 2 (1/2) days
