Three pipes x, y and z can fill a tank A can fill it in 4 minutes. Two pipes p and q are connected to tank B. how much time does it take for both tanks to run at the full capacity? Ratio of time taken to fill tank A by P and time taken by x to fill tank A is 2: 1 and ratio of time taken by Q to fill tank B and Z to fill tank A is 5: 3. Pipe P is 20% more efficient then pipe Q. and pipe Y takes 12 minutes to fill the tank. Capacity of tank B is 3/4 times of tank A. Note: Tank B is to be filled only after filling tank A. Valves of pipe p and q are closed once tank B is running at full capacity.
Two pipes are connected to tank 1 and one pipe connects tank 1 and tank 2 at the bottom of both tanks. At first pipe A and pipe B will filling tank 1 and then pipe C would be opened to fill tank 2. Capacity of tank 1 is twice capacity of tank 2. Pipe C takes 8 minutes to fill the whole tank 2 wherein discharging capacity of pipe C is 62.5 liters per minute. Ratio of time taken by pipe A and B to fill the tank when operating alone is 4 : 5 then find approximate discharging capacity of pipe A and B in liters/ minute if both the pipes discharge equal amount of water in tank. Time taken by pipe A and B to fill the tank 1 is 20/ 3 minutes
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Pipe A takes thrice the time taken by Pipe B to fill a tank. Together they can fill the tank in 15 hours, tank A and B is opened together for 4 hours and then Pipe A is closed and after 2 more hours Pipe B is closed and an outlet Pipe C is opened which when working alone can empty the tank in 10 hours. Calculate the time taken by C to empty the tank. Quantity B: A pipe A can fill the tank in 10 hours another pipe B can fill the tank in 15 hours and with the help of third pipe C they can fill the tank in 5 hours. Pipe A is opened for 4 hours then it is closed, pipe B is closed 3 hours before filling of tank and tank C is opened the whole time. Calculate the time taken to fill the tank

The average weight of a class of 12 students is 57 kgs. Two students of weights 48 kgs and 68 kgs are replaced by 2 new students having weights 52 kgs and 55 kgs. What is the new average weight of the class?
Pipes A and B are used to fill the tank. A can fill the tank twice as fast as B. Pipe C and D can empty the tank. D takes same time to empty the tank as taken by B to fill it. Pipe C can empty tank in 6 hours. If all 4 are opened together, how much hour would it take to fill the tank? (Assume: D can empty tank twice as fast as C.)
Pipe A requires 50% less time to fill up the tank then pipe C. Ratio of time required by pipe B to fill up the tank and time required by pipe C to fill up the tank is 4 : 5. If total time taken to fill up the tank is 4 minutes when all the pipes are open. Find the difference between time taken by C and time taken by B to fill up the tank.
Pipe A can fill a tank in 2/3 the time required by pipe B to fill the same tank. When an outlet pipe C is also opened with A and B, then it take 2/3 more time than what A and B takes to fill the tank. If, all the three pipes together take 18hrs to fill the tank, then in what time can C empty the tank?
A, B and C are 3 small pumps fitted to a tank. D is a large pump fitted to the tank. B is 50% more efficient than A. C is 33.33% more efficient than B. D is 50% more efficient than C. All of the pumps are used to fill the tank. Find the ratio of the time taken by all the pumps to fill the tank when pump D is used to empty the tank and other are used to fill the tank to the time taken when all are used to fill the tank?
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: There are two inlet pipes A, B and two outlet pipes C, D inlet pipe B takes 7 hours more to fill the tank when compared to A. Two outlet pipes when working together can empty the tank in 3.5 hours and efficiency of both the pipe is same if all of them working together can fill the tank in 2 hours. Calculate the time taken by A to fill the tank. Quantity B: The ratio of efficiencies of two pipes A and B is in the ratio 3 ∶ 2 and that of pipe B and C is 1 ∶ 3. Pipe A and B are inlet pipes, pipe C is outlet pipe working together they can fill the tank in 7.5 hours. Calculate the time taken by A to fill the tank when working alone.
