Directions: Study the following information carefully and answer the q...
From common explanation, we have

Hence, Option C is correct.
Common explanation:
Let the total students = 100x
The number of girls in the 9th class is 10% of the total number of students in the school.
Girls in the 9th class = 10% of 100x = 10x
                    
The number of girls in 10th class and in 12th class is 80% and 350% of the number of girls in 9th class.
Girls in 10th class = 80% of 10x = 8x
Girls in 12th class = 350% of 10x = 35x
The number of girls in the 11th class is 312.50% of the number of girls in the 10th class.


In the 10th class, there are 80% girls.

The ratio of the number of girls to the number of boys in the 9th class is 2 : 1.

The ratio of the number of boys in the 10th class to that in the 12th class is 1 : 3.

Boys in 11th class = 22x – (2x + 5x + 6x) = 9x

To solve this problem, let's break down the given information and solve step by step:

Given information:
- There are 4 classes in the school: 9th, 10th, 11th, and 12th.
- The ratio of boys in the 10th class to boys in the 12th class is 1:3.
- The ratio of girls to boys in the 9th class is 2:1.
- In the 10th class, 80% of the students are girls.
- The number of girls in the 11th class is 312.50% of the number of girls in the 10th class.
- The number of girls in the 10th class and 12th class is 80% and 350% respectively of the number of girls in the 9th class.
- The number of girls in the 9th class is 10% of the total number of students in the school.

Let's solve step by step:

Step 1: Find the number of girls in the 9th class.
- Let the total number of students in the school be x.
- As given, the number of girls in the 9th class is 10% of x.
- Therefore, the number of girls in the 9th class = (10/100) * x = x/10.

Step 2: Find the number of girls in the 10th class.
- As given, the number of girls in the 10th class is 80% of the total students in the 10th class.
- Let the total number of students in the 10th class be y.
- Therefore, the number of girls in the 10th class = (80/100) * y = 4y/5.

Step 3: Find the number of girls in the 12th class.
- As given, the number of girls in the 12th class is 350% of the number of girls in the 9th class.
- Therefore, the number of girls in the 12th class = (350/100) * (x/10) = 7x/20.

Step 4: Find the number of boys in the 12th class.
- As given, the ratio of boys in the 10th class to boys in the 12th class is 1:3.
- Let the number of boys in the 10th class be b.
- Therefore, the number of boys in the 12th class = (3/1) * b = 3b.

Step 5: Find the difference between the number of girls in the 11th class and the number of boys in the 12th class.
- As given, the number of girls in the 11th class is 312.50% of the number of girls in the 10th class.
- Therefore, the number of girls in the 11th class = (312.50/100) * (4y/5) = 5y.

- The difference between the number of girls in the 11th class and the number of boys in the 12th class is given as 76.
- Therefore, 5y - 3b = 76.

Step 6: Find the number of boys in the school.
- We need to find the value of b, which represents
