There are 12 pipes connected to a tank. Some of them are fill pipes and other are drain pipes. Each of the fill pipes can fill the tank in 8 hours and each of the drain pipes can drain completely in 6 hours. If all the pipes are kept open, an empty tank get filled in 24 hours. How many of the 12 pipes are filled pipes?
Malleable cast iron is produced 1. By quick cooling of cast iron. 2. By adding magnesium to molten cast iron. 3. from white cost iron by annealing. Which of the above statements is/are correct?
Five pipes P, Q, R, S, and T can fill a tank in 60 minutes, 20 minutes, 30 minutes, 8 minutes, 32 minutes respectively. Out of these five pipes, two have now been converted into emptying pipes such that their efficiency remains the same. When only one of the filling pipes and one of the emptying pipes operate, the tank can be filled in 60 minutes while another combination of emptying and filling pipe empties it in 8/45th of the time taken by the previous combination to fill the tank. Which pipes are converted into emptying pipes?
A set A of 6 pipes can fill the 60% of the tank in 6 minutes, another set B of 5 pipes can fill ¼ of the same tank in 4 minutes and a third set C of 4 pipes can empty ½ of the same tank in 8 minutes. If the efficiency of 2 pipes among the third set of pipes is increased to twice then find the per minute rate (in %) at which the tank will be full completely if all these 15 pipes are opened together?
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.

Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: No plastic is iron. All steel is iron. Conclusions: I. Some plastic is steel. II. Some iron is steel. III. No steel is plastic.
Pipes A and C together can fill a tank in 26(2/3) hours and pipes B and C together can fill a tank in 48 hours. Pipes A and B are inlet pipes and pipe C is an outlet pipe. If all the three pipes are opened together, then in what time the tank will be filled?
A water tank has two types of inlet pipe viz. Type A and type B. 5 inlet pipes of type A and 25 pipe of type B are opened, the tank is filled in 30 minutes. Whereas it takes 1 hour if 3 pipes of type A and 12 pipes of type B are opened. In how many minutes does empty tank is filled by 8 pipes of type A and 12 pipes of type B.
A tank can be filled using pipes A, B, and C and can be emptied using pipe D. Pipes A & B can together fill the tank in 8 hours, pipes B & C can together fill the tank in 10 hours and pipes A & C can together fill the tank in 6 hours. If pipe D can alone empty the tank in 15 hours, in how much time will the tank be filled if all the pipes are simultaneously opened?
Which of the following statements are correct? 1. Steel and cast iron are multi-phase alloys. 2. Ferrite is a single phase interstitial solid solution of carbon in iron. 3. Wrought iron is a highly refined iron with a small amount of slag which gives resistance to progressive corrosion. 4. Stellite contains large amounts of metals like cobalt and tungsten resulting in high hardness. Select the correct answer using the code given below.
