A pipe can fill an empty tank in 12 min and another pipe can fill it in 24 min. If both the pipes are kept open simulteneously, then in how many minutes will the tank get filled?

Explanation

To solve the problem of how long it will take to fill the tank when both pipes are open simultaneously, we can follow these steps:

### Step 1: Determine the filling rates of each pipe.
- Pipe A can fill the tank in 12 minutes. Therefore, its filling rate is:
\[ \text{Rate of Pipe A} = \frac{1 \text{ tank}}{12 \text{ minutes}} = \frac{1}{12} \text{ tanks per minute} \]
