C) 10 days
D) 11.3 days
E) 12.7 days
Work done by 2 men and 3 women in 1 day = 1/10   Work done by 3 men and 2 women in 1 day = 1/8   Let 1 men does m work in 1 day and 1 women does w work in 1 day. The above equations can be written as   2 m + 3 w = 1/10 ---(1)   3 m + 2 w = 1/8 ---(2)   Solving equation (1) and (2) , we get m=14/200 and w=1/100   2 men and 1 woman together can finish the work in =14/200+1/100=2/25=12.5 days   12.5 days
