Identifying Students Scoring $\ge$ 70% in At Least 4 Subjects
The question asks us to count the number of students who have achieved a score of 70% or more in a minimum of 4 subjects. We need to examine the performance of each student based on the provided table.
Student Performance Analysis
We will check each student's marks subject by subject to count how many subjects meet the condition ($\ge 70\%$).
- Student A: Scored $\ge 70\%$ in English (80%), Sociology (80%), Psychology (70%), and IT (80%). This is a total of 4 subjects. Student A meets the condition.
- Student B: Scored $\ge 70\%$ in English (90%), Economics (80%), Sociology (70%), Psychology (80%), and IT (70%). This is a total of 5 subjects. Student B meets the condition.
- Student C: Scored $\ge 70\%$ in English (80%), Sociology (70%), Philosophy (70%), Psychology (80%), and IT (70%). This is a total of 5 subjects. Student C meets the condition.
- Student D: Scored $\ge 70\%$ in English (70%), Sociology (80%), and Philosophy (80%). This is a total of 3 subjects. Student D does not meet the condition.
- Student E: Scored $\ge 70\%$ in English (70%), Sociology (80%), Philosophy (75%), and IT (80%). This is a total of 4 subjects. Student E meets the condition.
- Student F: Scored $\ge 70\%$ in Economics (75%) and Philosophy (80%). This is a total of 2 subjects. Student F does not meet the condition.
- Student G: Scored $\ge 70\%$ in Philosophy (70%), Psychology (70%), and IT (70%). This is a total of 3 subjects. Student G does not meet the condition.
Counting Eligible Students
By analyzing each student's performance:
- Students meeting the criteria are A, B, C, and E.
- The total number of students who scored $\ge 70\%$ marks in at least 4 subjects is 4.
Therefore, 4 students satisfy the given condition.
