The figure shows Tap A, Tap B and an empty tank. Tap A can fill the empty tank in 12 minutes and Tap B can fill the empty tank in 6 minutes. Both taps are turned on at the same time. How long will it take for both taps to fill up the whole tank together?

Two water taps together can fill a tank in hours. The tap of the larger diameter takes 10 hours less than the smaller one to fill the tank separately. Find the time at which each tap can separately fill the tank.

Tap A can fill a tank in 8 hrs and tap B can fill the same tank in 6 hrs. If tap B and C are opened at the same time they will fill the tank in half time as tap A. How much time will tap C take to fill the tank alone?

A tap can fill a tank in 6 hours. After half the tank is filled, three more similar taps are opened. What is the total time taken to fill the tank completely?3 hrs 15 min3 hrs 45 min4 hrs4 hrs 15 min

Tap A alone fills a tank in 24 hours. Tap A and tap B together fill the same tank in 15 hours. Tap B alone can fill the tank in how many hours?

A tank has four emptying taps, all of equal efficiencies, but each fixed at th, th, th and th of the height of the tank respectively. Two filling taps, each of which individually can fill the tank in 200 minutes, are also connected to the tank. If the ratio of the efficiency of each emptying tap and the efficiency of each filling tap is 1 : 3, and all the six taps are opened simultaneously, in how much time will the empty tank be filled?
