Given Data:
- Pipe A fills the cistern in 8 hours.
- Pipe B can empty the cistern in 12 hours.
Approach:
- First, find the rate of filling of pipe A and rate of emptying of pipe B.
- Then, calculate the net rate of both pipes working together.
- Use the net rate to find the time taken to fill the cistern.
Calculation:
- Rate of filling by pipe A = 1/8 cistern/hour
- Rate of emptying by pipe B = 1/12 cistern/hour
- Net rate of filling when both pipes are open = (1/8) - (1/12) = 1/24 cistern/hour
- Time taken to fill the cistern when both pipes are open = 1 / (1/24) = 24 hours
Therefore, the cistern will be filled in 24 hours when both pipes A and B are open simultaneously. Hence, the correct answer is option 'B' (24 hrs).
