Quantitative Aptitude ( CCS) Pipes&cistern

Directions : Study the following pie charts carefully and answer the following questions given beside.

There are five inlet pipes (A, B, C, D, and E) and five outlet pipes (P, Q, R, S, and T) connected to a tank. The first pie-chart represents the percentage of the tank filled by each inlet pipe when all the inlet pipes are opened together and the second pie-chart represents the percentage of the tank emptied by each outlet pipe when all the outlet pipes are opened together.

Total capacity of the tank = 1200 litres

Time taken to fill the tank when all the inlet pipes are opened together = 3 minutes

Time taken to empty the tank when all the outlet pipes are opened together = 2.4 minutes

Find the ratio of the sum of the time taken by pipe C alone and time taken by pipe E alone to fill the tank to the sum of the time taken by pipe Q alone and time taken by T alone to empty the tank.

Explanation:

By using common explainantion :

Sum of the time taken by pipe C alone and time taken by pipe E alone to fill the tank = 12 + 10 = 22 minutes
Sum of the time taken by pipe Q alone and time taken by T alone to empty the tank = 8 + 24 = 32 minutes
Required ratio = 22 : 32 = 11 : 16
