Question

How many students get total marks in all subjects below 400 ?

• A. 3
• B. 5
• C. 4
• D. 6

Hint:

To score 400 or more across 5 subjects, a student must average at least 80 marks per subject. Looking at the table, you can quickly identify students who have mostly scores below 80 (Bhavin, Parth, Rudra, and Vaishali) without calculating every sum completely.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
To solve this question, we must calculate the total marks scored by each of the 8 students across all five subjects and then count how many of them scored less than 400.

Step 2: Detailed Explanation:
Let us calculate the total marks for each of the 8 students from the table:
1. Sarika:
\( \text{Total} = 87 + 78 + 77 + 87 + 80 = 409 \) (Not below 400)
2. Vedika:
\( \text{Total} = 86 + 80 + 82 + 74 + 79 = 401 \) (Not below 400)
3. Purvansh:
\( \text{Total} = 82 + 81 + 84 + 83 + 80 = 410 \) (Not below 400)
4. Bhavin:
\( \text{Total} = 74 + 78 + 70 + 77 + 80 = 379 \) (Below 400)
5. Parth:
\( \text{Total} = 70 + 74 + 72 + 75 + 72 = 363 \) (Below 400)
6. Rudra:
\( \text{Total} = 78 + 71 + 79 + 72 + 77 = 377 \) (Below 400)
7. Vaishali:
\( \text{Total} = 75 + 76 + 67 + 78 + 82 = 378 \) (Below 400)
8. Anjali:
\( \text{Total} = 85 + 82 + 75 + 84 + 79 = 405 \) (Not below 400)
Let us list the students with total marks below 400:
- Bhavin (379)
- Parth (363)
- Rudra (377)
- Vaishali (378)
The total number of students who scored below 400 is 4.

Step 3: Final Answer:
The correct option is (C).
