A bucket can be filled by two taps in 10 minutes and 15 minutes respectively. But due to some obstructions present in both the taps, the former delivers water at two-fifths of its capacity and the latter delivers at three-fifths of its capacity. But after a while the obstructions got removed and the bucket gets filled in 12 minutes from that moment. For how long did the taps deliver water with obstructions present in them?

Analysis:
To solve this problem, we need to consider the rate at which each tap fills the bucket both with and without obstructions. Let's break down the problem step by step:

Step 1: Calculate the rate of filling the bucket without obstructions
- Let the capacity of the bucket be C.
- The first tap fills the bucket at a rate of C/10 units per minute.
- The second tap fills the bucket at a rate of C/15 units per minute.

Step 2: Calculate the rate of filling the bucket with obstructions
- With obstructions, the first tap fills the bucket at a rate of 2/5 * C/10 = 2C/50 units per minute.
- With obstructions, the second tap fills the bucket at a rate of 3/5 * C/15 = 3C/75 units per minute.

Step 3: Determine the combined rate of filling the bucket with obstructions
- The combined rate of filling the bucket with obstructions is (2C/50) + (3C/75) = 7C/150 units per minute.

Step 4: Calculate the time taken to fill the bucket without obstructions
- The time taken to fill the bucket without obstructions is C / (7C/150) = 150/7 minutes.

Step 5: Calculate the time taken to fill the bucket with obstructions
- The time taken to fill the bucket with obstructions is 12 minutes.

Step 6: Calculate the time for which the taps delivered water with obstructions
- Let x be the time for which the taps delivered water with obstructions.
- Using the concept of work, we can set up the equation: x * (7C/150) = 12 * (C/10 + C/15)
- Solving this equation gives x = 5 minutes.
Therefore, the taps delivered water with obstructions for 5 minutes.

Conclusion:
- The correct answer is (D) 5 minutes.
