If Pipes A and B can fill a tank in 15 min and 20 mins respectively and pipe C empties the tank in 12 mins. what will be the time taken by A, B and C together to fill the tank completely?
Pipe A, B and C used to fill a tank. Pipe A and B fills the tank in 8 and 12 h respectively and pipe C can empty the tank in 6 h. Find the time taken to fill the tank, if all the three pipes are open.
Tap A can fill a tank in 4 hours and with help of tab B it takes 2.4 hours, tap B fill 14lit per min. Find capacity of tank?
Pipe A and pipe B together can fill the tank in 24 minutes, while pipe A, pipe B and pipe C together can fill the tank in 30 minutes and Pipe B and Pipe C together can fill the tank in 60 minutes. In how many minutes pipe A alone can fill the same tank completely.
Pipe P alone takes 20% less time than that of pipe Q alone to fill a tank. When both pipes together open for 8 hours in the same tank, then 90% of the tank filled. Find difference between their individual time to fill the same tank?
Pipe A and B alone can fill a tank in ‘x’ hours and ‘x+10’ hours respectively. If both pipes together fill the tank in 12 hours, then the time taken by B alone to fill the tank is what percent of that of A alone?
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).
