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

Three filling pipes, R, S and T, together, can fill an empty tank in two hours. S can fill the tank four times as fast as T. Initially, R alone is opened and after exactly x hours, it is closed and immediately S and T are opened together. The tank is full after exactly another y hours. If the tank was filled in a total of 4 hours, and x ≠ y, find the time (in hours) that T alone would take to fill the tank.6201224
