Ratio and ProportionDate: 7/4/96 at 19:21:20 From: Anonymous Subject: Ratio and Proportion Six men can complete a piece of work in one day while 5 boys would take 2 days to complete the same piece of job. 44 men can build a tower in 5 days; how long will 40 men and 80 boys take to build the tower? Date: 7/5/96 at 8:37:52 From: Doctor Anthony Subject: Re: Ratio and Proportion From the first statement, 3 men would take 2 days to do the job. It follows that 5 boys are equivalent to 3 men. Since we have 80 boys building the tower, these boys are equivalent to (3/5)*80 = 48 men. So the total workforce on the tower is equivalent to 40+48 = 88 men If 44 men take 5 days, then 88 men would take 5/2 = 2 +1/2 days. -Doctor Anthony, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
