Pipes P, Q and R together can fill a tank in 5 minutes and pipes P and Q together can fill the tank in 10 minutes. Find the time taken by pipe R alone to fill the tank.
A, B & C are three pipes. Pipe B can fill a tank in 30 hours and ratio of efficiency of A to B is 3:4. If pipe A and B open for ten hours and remaining tank fill by pipe C. If total time taken to fill the tank is 15 hours, then find the time taken by C alone to fill the tank (in hour).
Pipe M can fill 3/4th of tank P in 45 minutes, and pipe N can fill 80% of the tank in 40 minutes. If the capacity of tank Q is 50% less than that of tank P and the efficiency of pipe N is decreased by 25%, then find the time (in minutes) taken by pipes M and N together to fill tank Q (approx.).
Pipe X alone can fill the tank in 20 minutes, and pipes X and Y together can fill the tank in 12 minutes. If the efficiency of pipe Z is 75% that of pipe Y, find the time taken by pipes X and Z together to fill the tank (in minutes).
