A bath can be filled by the cold water pipe in 20 minutes and by the hot water pipe in 30 minutes. A person leaves the bathroom after turning on both pipes simultaneously and returns at the moment when the bath should be full. Finding, however, that the waste pipe has been open, he now closes it.In 6 minutes more the bath is full. In what time would the waste pipe empty it? A water tank is two-fifth full.Pipe A can fill a tank in 10 minutes and pipe B can empty it in 6 minutes.If both the pipes are open,how long will it take to empty or fill the tank completely? Pipes A and B can fill a cistern in 15 hours together. But ifthese pipes operate separately A takes 40 hours less than Bto fill the tank. In how many hours the pipe A will fill thecistern working alone? Two pipes A and B can fill a tank in 12 and 24 minutes respectively. If both the pipes are used together, how long will it take to fill the tank? Two pipes A and B can fill a cistern in 37.5 minutes and 45 minutes respectively. This cistern will be filled in half an hour if both the pipes are opened together initially and pipe B is then turned off after X minutes. What is X? Tap X can fill a cistern in 10 minutes and tap Y can fill in 12 minutes. There is a leakage in the bottom of the cistern that empties the tank in 24 minutes. If both taps X and Y are opened together, then how long will it take to fill the cistern? Half of the water tank is filled manually. Tap A can fill the tank in 20 minutes and B can empty the tank in 12 minutes. If A and B are opened together, then the time taken to empty or fill the tank is: Three taps A,B and C are used to fill a cistern. Tap A alone can fill the cistern in 9 minutes. Tap B can fill in 6 minutes and Tap C can fill in 3 minutes. How many minutes will it take to fill this cistern if all the three taps are used simultaneously? A Pipe P can fill a tank in 16 minutes and the other pipe Q can empty the whole tank in 32 minutes. If both P and Q are opened simultaneouly then the time taken to fill the tank is: Two taps can fill a cistern in 30 and 40 minutes respectively. If both the taps are opened simultaneously then the approximate time taken to fill the cistern is:
