In a class, the average marks got by number of students in English is ...
D) 51.8
Explanation: Let there are 100 students in the class, then in category A = 20 students, in C = 25 students, remaining = 55 students. Let x be the average of these 55 students.
So 20*80+ 25*31 + 55*x = 52.25*100

In a class, the average marks got by number of students in English is ...
Given:
- The average marks of all students in English is 52.25.
- 25% students in the class (placed in C category) have an average of 31 marks.
- 20% students (placed in A category) have an average of 80 marks.

To find:
- The average marks of the remaining students.

Solution:
Let's assume that there are a total of 100 students in the class. Then:
- 25 students (25% of 100) are placed in C category, and their total marks = 25 * 31 = 775.
- 20 students (20% of 100) are placed in A category, and their total marks = 20 * 80 = 1600.

The total marks of all students = 100 * 52.25 = 5225.
So, the total marks of the remaining students = 5225 - 775 - 1600 = 2850.

The number of remaining students = 100 - 25 - 20 = 55.
Therefore, the average marks of the remaining students = 2850 / 55 = 51.81 (approx).

Hence, the correct option is D (51.8).

Note: The assumption of 100 students was made for ease of calculation. The same method can be applied for any given number of students.
