15 men take 21 days of 8 hrs. each to do a piece of work. How many days of 6 hrs. each would it take for 21 women if 3 women do as much work as 2 men? : Find the no. of man-hrs to complete the job 15 * 21 * 8 = 2520 man hrs : 2 man-hrs = 3 women-hrs therefore 1 women-hr = 2/3 man-hr : let d = no. days for these women to do the job 21 * 2/3 * 6d = 2520 84d = 2520 d = 30 days
30 days im not 100% sure.. but i used de logic M1*D1*T1=M2*D2*T2 Given M1=15, D1=21, T1=8hrs, M2=14(21 women=14 men),T2=6hrs, Therefore, D2= M1*D1*T1 / M2*T2=30
