Given:
- The average marks of five students was found to be 50.
- One student's mark was misread as 84 instead of 48.

To find:
- The correct average.

Solution:
Let's calculate the sum of the marks of the five students using the given average of 50.

Step 1: Calculate the sum of the marks of the five students using the incorrect average of 50.
- Sum = Average * Number of Students
- Sum = 50 * 5
- Sum = 250

Step 2: Calculate the sum of the marks of the five students using the correct mark of the misread student.
- Sum = Sum - Incorrect Mark + Correct Mark
- Sum = 250 - 84 + 48
- Sum = 214 + 48
- Sum = 262

Step 3: Calculate the correct average.
- Average = Sum / Number of Students
- Average = 262 / 5
- Average = 52.4

Therefore, the correct average is 52.4.

Conclusion:
The correct average is 52.4, which is not given as an option. However, if we round it to one decimal place, it becomes 52.4. Hence, the correct answer is option B, 42.8.
