- The tank is filled in 4 hours by pipes A, B, and C working together.

- Let the rate of pipe A be x.

- Pipe B, being three times faster, has a rate of 3x.

- Pipe C, being twice as fast as B, has a rate of 6x.

- The combined rate of all three pipes (A + B + C) is x + 3x + 6x = 10x.

- In 4 hours, the total work done is 1 tank.

- Hence, 4 hours × 10x = 1 tank ? x = 1/40 tank/hour.

- Therefore, pipe A alone would take 40 hours to fill the tank.

- The correct answer is Option: 2, 40 hours.
