Answer by jorel555(1290)   (Show Source):
You can put this solution on YOUR website! You have 5 men, 20 women, and 40 boys. 10 men, 10 women, and 20 boys gives you twice the men, but 1/2 the women and boys. 2x1/2x1/2=1/2 of the work force you had before, thereby doubling the amount of days. But, your workday is longer by 3/2, so you need 2/3 the time of your first work day. 2/3x240=160 days needed to do the piece of work!!!!!!!!!!!
