A water tank has three taps: A, B and C. A fills four buckets in 24 minutes, B fills 8 buckets in 1 hour and C fills 2 buckets in 20 minutes. If all the taps are opened together, a full tank is emptied in 2 hours. If a bucket can hold 5 liters of water, what is the capacity of the tank in liters ?

Three taps have diameters of 1 cm, 4/3 cm, and 2 cm respectively. The rate of water flow through each tap is proportional to the square of its diameter. The tap with the largest diameter can fill the tank by itself in 61 minutes. If all three taps are opened together, how long will it take to fill the tank completely ?
