A Time taken by pipe P and Q to fill the tank is 120/23 minutes. Time taken by drain pipe S to empty the tank is 12 minutes more than pipe P to fill the tank. Time taken by pipe Q is 15 minutes. Ratio of time taken by R to fill up the tank and by pipe Q is 4 : 5. What is total time taken to fill the whole tank when all the pipes are open? 
Time taken by pipe A and pipe B to fill up the cistern is 12 minutes whereas time taken by pipe C to empty the whole cistern is twice that of time taken by A and B together to fill the tank and ratio of time taken by pipe A and B to fill up the tank when operating alone is 2 : 3. If pipe A and B are alternatively opened every 6 minutes and C is opened with pipe B but closed when pipe A is opened then calculate total time taken to fill up the whole cistern. 
A can finish a work in half the time taken by B to finish the work. The time taken by C to finish the work is equal to the total time taken by A and B together to finish the work. What is the ratio of the time taken to finish the work when A, B and C work together to that of the time taken by A working alone?
If the sum of the total time taken by boats X1 to travel D km each upstream and X2 to travel downstream is 4 hours and the sum of the total time taken by boats X1 to travel downstream and X2 to travel upstream the same distance D km each is 12 hours. Time taken by X2 to travel upstream exceeds its downstream time by t1 hours. Similarly, the time taken by X1 to travel upstream exceeds its downstream time by t2 hours. What is the value of (t1 - t2)?
In a public bathroom there are n taps 1,2,3...n. Tap1 and Tap2 take equal time to fill the tank while Tap3 takes half the time taken by Tap2 and Tap4 takes half the time taken by Tap3. Similarly each next number of tap takes half the time taken by previous number of Tap i.e, K-th Tap takes half the time taken by (K-1)th Tap.If the 10th tap takes 2 hours to fill the tank alone then what is the ratio of efficiency of 8th tap and 12th tap, respectively?
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.
Time taken by pipe P and Q to fill up the tank is 60/ 7 minutes and time taken to fill the whole tank when all three pipes are open is 300/ 23 minutes. Ratio of time taken by pipe P to fill up the tank and pipe Q is 3 : 4. Calculate time taken by Q and R to fill up the tank. (Pipe R is a drain pipe.)
