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.
| Student | Subject (Max. Marks) | |||||
| Maths | Chemistry | Physics | Geography | History | Computer Science | |
| (150) | (130) | (120) | (100) | (60) | (40) | |
| Ayush | 90 | 50 | 90 | 60 | 70 | 80 |
| Aman | 100 | 80 | 80 | 40 | 80 | 70 |
| Sajal | 90 | 60 | 70 | 70 | 90 | 70 |
| Rohit | 80 | 65 | 80 | 80 | 60 | 60 |
| Muskan | 80 | 65 | 85 | 95 | 50 | 90 |
| Tanvi | 70 | 75 | 65 | 85 | 40 | 60 |
| Tarun | 65 | 35 | 50 | 77 | 80 | 80 |
5.
What is the overall percentage of Tarun?
Answer: Option
Explanation:
Aggregate marks obtained by Tarun
= [ (65% of 150) + (35% of 130) + (50% of 120)
+ ((77% of 100) + (80% of 60) + (80% of 40) ]
= [ 97.5 + 45.5 + 60 + 77 + 48 + 32 ]
= 360.
The maximum marks (of all the six subjects)
= (150 + 130 + 120 + 100 + 60 + 40)
= 600.
 Overall percentage of Tarun = |
 |
360 | x 100 |  |
% = 60%. |
| 600 |

@David.
The question is overall percentage NOT overall marks, so you need to find the % overall.

@Rita.
This 60 you got is average marks of all 6 subs if all subjects are of equal weight. Which is not asked in the question?
We need a percentage of marks (all sub having different weights) so we take aggregate.
Marks and divide by total marks achievable.

No, 360 are marks not % and we can do following calculations.
i.e 360/6 = 60 it is right.
i.e 360/6 = 60 it is right.

@David.
Because 360 are not the marks 360 are the % that's why.

Why not aggregate marks divided by total number of subjects:
i.e. 360/6 = 60.
i.e. 360/6 = 60.

Percentage calculation simplification:
1% = 00 (two zeros) i.e. if we see one % symbol we can cancel two zeros.
If we find 2% symbols we can cancel zeros.
For ex: 90%150 = 9*15 = 135.
= 99%88 = 87.12.
