(1) 10 days (2) 2 days (3) 5 days (4) 8 days (5) None of these Answer by knighty2002uk(39) (Show Source):
You can put this solution on YOUR website! Wordy answer but here goes.
12 women take 5 days to do one item. Therefore each woman contributed 1/60th of the item per day.
3 women working for 10 days = 30/60ths of the item = 1/2.
9 children therefore make 1/2 an item in 10 days.
36 children will make 2 items in 10 days, so they can make 1 item in 5 days.
(answer is (3) 5 days)
