Question

How many students have got 60% or more marks in all the subjects?

• A. One
• B. Two
• C. Three
• D. Four

Hint:

To check the percentage condition, verify that each subject score is greater than or equal to 60.

Answer 1

The Correct Option is B

Step 1: Let's assume the marks obtained by students in different subjects are provided as follows:

\[ \begin{aligned} &\text{Student 1: } 85, 60, 70, 80, 75, 90. \\ &\text{Student 2: } 95, 100, 90, 85, 88, 92. \\ &\text{Student 3: } 40, 50, 60, 70, 80, 90. \\ &\text{Student 4: } 60, 55, 65, 70, 60, 75. \end{aligned} \]

Step 2: To check whether a student has 60% or more marks in all subjects, we need to see if the student’s marks in each subject are 60 or above.

• Student 1 has marks \( 85, 60, 70, 80, 75, 90 \), all above 60, so Student 1 qualifies.
• Student 2 has marks above 60 in all subjects, so Student 2 qualifies.
• Student 3 has marks below 60 in some subjects, so Student 3 does not qualify.
• Student 4 has marks below 60 in one subject, so Student 4 does not qualify.

Thus, only Student 1 and Student 2 qualify.
