**Calculating the New Median in a Continuous Frequency Distribution**

In order to find the new median of a continuous frequency distribution, where each observation is increased by a certain value, we need to follow a step-by-step process. Let's consider the given scenario and solve it step by step:

**Step 1: Understand the Problem**
We are given a continuous frequency distribution, and we know that the median of the data is 21. We need to find the new median if each observation is increased by 5.

**Step 2: Analyze the Given Data**
In a continuous frequency distribution, we have a set of class intervals with their respective frequencies. However, in this particular question, we are not given the class intervals or frequencies. Therefore, we will assume that we have a frequency distribution table and proceed with the solution.

**Step 3: Determine the Original Median**
Since the median is the middle value of a data set, we need to determine the cumulative frequency that corresponds to the median. The cumulative frequency is the sum of all frequencies up to a particular class interval. We need to find the class interval that contains the median value.

**Step 4: Calculate the Original Median**
To find the original median, we need to use the formula:

Median = L + ((N/2 - CF) x C) / f

Where:
L = Lower limit of the median class
N = Total number of observations
CF = Cumulative frequency up to the median class
C = Width of the class interval
f = Frequency of the median class

We substitute the given values into the formula and calculate the original median.

**Step 5: Increase Each Observation by 5**
We are given that each observation is increased by 5. Therefore, we add 5 to each value in the data set.

**Step 6: Determine the New Median**
To find the new median, we repeat the same process as in Step 3 and Step 4, but this time using the updated data set.

**Step 7: Calculate the New Median**
Using the formula mentioned in Step 4, we calculate the new median with the updated data set.

**Step 8: Final Answer**
After calculating the new median, we obtain the final answer, which will be the new median value.

By following this step-by-step process, we can determine the new median of a continuous frequency distribution when each observation is increased by a certain value.
