Given Information:
- Pipe P takes half as much time as pipe Q alone or one third as much time as pipe R alone to fill the tank completely.
- Pipe Q is closed after half an hour.
- Pipes P and R filled the remaining one twelfth of the tank in 3.75 minutes.

Calculations:
1. Let's assume:
- Pipe Q alone takes x hours to fill the tank.
- Pipe P takes x/2 hours to fill the tank.
- Pipe R takes 3x hours to fill the tank.
2. In 30 minutes (0.5 hours):
- Pipe Q fills 1/2x of the tank.
- Pipe P fills 1/4x of the tank.
- Pipe R fills 3/2x of the tank.
3. After half an hour, the remaining tank is 1 - (1/2 + 1/4) = 1/4.
- Pipes P and R fill 1/12 of the tank in 3.75 minutes (3.75/60 = 0.0625 hours).
- P and R together fill 1/12 of the tank in 0.0625 hours.
- P fills 1/4x in 0.5 hours, so it fills 1/16x in 0.0625 hours.
- R fills 3/2x in 0.5 hours, so it fills 3/32x in 0.0625 hours.
- Therefore, 1/16x + 3/32x = 1/12.
- Solving this equation gives x = 0.25.

Time taken by Pipe P alone to fill the tank:
- Pipe P takes x/2 = 0.25/2 = 0.125 hours.
- Pipe P alone takes 0.125 hours or 7.5 minutes to fill the tank completely.
