hours, respectively, while working alone. If the two pipes are opened together, the time taken to fill the cistern is:Solution
Two pipes, D and E, can fill a cistern in 26 and 78 hours, respectively, while working alone. LCM of 26 and 78 is 78 which can be assumed as the total work. Efficiency of D = 78/26 = 3 units/hour Efficiency of E = 78/78 = 1 unit/hour If the two pipes are opened together, the time taken to fill the cistern = 78/(3+1) = 78/4 =Â 19.5 =Â 19(1/2) hours
