If 3 men or 4 women can do a piece of work in 16 days, in how many days can 12 men and 8 women do the same piece of work?	Choices:
A) 8/3	B) 6	C) 5	D) 4	E) 3
3 men can finish a work in 16 days, so in 1 day 3 men finish 1/16th of work and in 1 day 1 men can finish, 1/48th of work.   similarly, in 1 day 1 women can finish 1/64th of work.   12 men in 1 day can finish, 12/48 = 1/4,   8 women in 1 day can finish = 8/64 = 1/8   1/4 + 1/8 = 3/8.   hence number of days to complete is 8/3 days.   8/3NSWER:8/3
