সঠিক উত্তর
2 (18 hours)
বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Given:
- Time taken by Pipe P = 24 hours
- Time taken by Pipe Q = 72 hours (since Pipe Q takes 3 times more than Pipe P)
Time taken by both pipes together = (24 × 72) / (24 + 72)
Time taken by both pipes together = 1728 / 96 = 18 hours
∴ Time taken by both pipes to fill the tank is: 18 hours
