Pipe A can fill an empty tank in 30 minutes, Pipe B can empty the same filled tank in 2 hours and Pipe C can empty the same filled tank in 5 hours. If all these are opened together when the tank is empty, then in how many hours will the tank be filled?
An empty vessel was first filled with alcohol. When the vessel got 1/4th empty, it was filled with spirit. Again, when the vessel got 1/3rd empty, it was filled with alcohol. Again when the vessel got 1/5th empty, it was filled with spirit. Find the percentage of spirit in the vessel.

Pipes X and Y are the filling pipes while Z is an empty pipe. X, Y can fill the given empty tank In 45 and 54 minutes respectively. However, pipe Z can empty in 90 minutes. If all the pipes are opened Together for 10 minutes after that pipe is A and B is blocked and Now, only pipe Z is opened. Find the total time taken by pipe Z to empty the filled tank?
A pipe, working at full speed, can fill an empty cistern in 1 hour. However, during the first hour it worked at one-twenty-fourth of its capacity, during the second hour at one-twelfth of its capacity, during the third hour at one-eighth of its usual capacity, during the fourth hours at one-fourth of its usual capacity and during the fifth hour it was only one-half as efficient as it was supposed to be. A second pipe also displayed similar performance, but if it worked at full speed would have filled the empty cistern in 2 hours. Together with a drain pipe that drained water out of the tank a constant rate, the empty cistern could be filled in 5 hours, all the three pipe working concurrently. How many hours will it take the drain pipe to empty the filled cistern if no other pipe was functioning during the time?
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.)
Processes P1 and P2 have a producer-consumer relationship, communicating by the use of a set of shared buffers. P1: repeat                 Obtain a full buffer                 Empty it                 Return an empty buffer forever P2 P2P2: repeat             Obtain a full buffer             Empty it             Return an empty buffer          forever Increasing the number of buffers is likely to do which of the following? I. Increase the rate at which requests are satisfied (throughput) II. Decrease the likelihood of deadlock III. Increase the ease of achieving a correct implementation
