The following table gives the percentage of marks obtained by seven students in six different subjects in an examination. The Numbers in the Brackets give the Maximum Marks in Each Subject.
The number of students who obtained 60% and above marks in all subjects is?
- A.
1
- B.
2
- C.
3
- D.
None
Show answer & explanation
Correct answer: B
In a 'X% or above in every subject' data-interpretation question, a student qualifies only if EVERY value in that student's row across all subjects meets the cutoff — a single subject below the cutoff disqualifies the student no matter how high the other subjects are. Here the table already reports percentages, so the bracketed maximum marks are not needed for this particular question; they would matter only for a variant asking for the raw marks obtained.
Applying the 60% cutoff to each student's six subject percentages:
Student | Maths | Chemistry | Physics | Geography | History | Computer Science | Meets 60% in every subject? |
|---|---|---|---|---|---|---|---|
Ayush | 90 | 50 | 90 | 60 | 70 | 80 | No — Chemistry is 50% |
Aman | 100 | 80 | 80 | 40 | 80 | 70 | No — Geography is 40% |
Sajal | 90 | 60 | 70 | 70 | 90 | 70 | Yes |
Rohit | 80 | 65 | 80 | 80 | 60 | 60 | Yes |
Muskan | 80 | 65 | 85 | 95 | 50 | 90 | No — History is 50% |
Tanvi | 70 | 75 | 65 | 85 | 40 | 60 | No — History is 40% |
Tarun | 65 | 35 | 50 | 77 | 80 | 80 | No — Chemistry is 35% and Physics is 50% |
Cross-check using each student's LOWEST subject percentage: a student clears the cutoff throughout only if this row-minimum is at least 60%. Sajal's lowest value is 60% (Chemistry) and Rohit's lowest value is 60% (History and Computer Science tie at 60%) — both row-minimums sit exactly at the cutoff, so neither student dips below it anywhere. Every other student's row-minimum is below 60%, which rules them out.
So exactly two students — Sajal and Rohit — obtain 60% or more marks in every one of the six subjects, making the correct count 2.
