Study the following table carefully to answer the question
Marks obtained by the students in different subjects at board examination.
| Subject (Marks) / Student | Math (75) | Science (75) | English (80) | Hindi (60) | Computer (110) |
|---|---|---|---|---|---|
| PK | 60 | 62 | 70 | 50 | 90 |
| QS | 48 | 56 | 70 | 55 | 90 |
| RP | 70 | 68 | 72 | 40 | 80 |
| SG | 62 | 69 | 75 | 45 | 95 |
| GP | 66 | 60 | 62 | 30 | 85 |
| FA | 54 | 70 | 50 | 56 | 100 |
What is the overall percentage of marks obtained by GP in all subjects?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 75.75%
The overall percentage compares GP’s total with the total maximum marks, which are the figures in brackets in the heading row: 75, 75, 80, 60 and 110.
GP’s total: \(66+60+62+30+85=303\)
Maximum marks: \(75+75+80+60+110=400\)
Percentage \(\displaystyle =\frac{303}{400}\times100=75.75\%\)
Tip: Divide by the maximum marks of all five subjects together, not by 5 \(\times\) 100; the subjects here are marked out of different totals.
