| 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 |

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