Read the given information and answer the question that follows.
The following table gives the percentage of marks obtained by seven students in six different subjects in an examination.
The number in the brackets give the maximum marks in each subject.

Subject (Max. Marks)
Student	Maths (150)	Chemistry (130)	Physics (120)	Geography (100)	History (60)	Computer Science (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

If someone secured all the highest scores that have been obtained by some student or the other in the six subjects as given in the table above, what would be the exact overall percentage score obtained by that student?

Correct option is A

Given:

The percentage of marks obtained by seven students in six different subjects in an examination

Solution:

In Maths highest marks is scored by Aman = 100%

Maximum marks for Maths =150

Marks scored = 100% of 150 = 150 marks

In Chemistry highest marks is scored by Aman = 80%

Maximum marks for Chemistry =130

Marks scored = 80% of 130 = 104

In Physics highest marks is scored by Ayush =90%

Maximum marks for Physics =120

Marks scored = 90% of 120 = 108

In Geography highest marks is scored by Muskan = 95%

Maximum marks for Geography = 100

Marks scored = 95% of 100 = 95

In History highest marks is scored by Sajal = 90%

Maximum marks for History = 60

Marks scored = 90% of 60 =54

In Computer Science highest marks is scored by Muskan = 90%

Maximum marks for Computer Science = 40

Marks scored = 90% of 40 = 36 marks

Total of highest marks scored = 150+104+108+95+54+36 = 547

Total of maximum marks for all subjects = 150 + 130 + 120 + 100 + 60 + 40 = 600

Percentage of marks = $$\frac{547}{600}\times 100 = 91\frac{1}{6}\%$$ 

Confusion Point: ​

In the table the given marks obtain are in percentage of maximum marks not the actual marks so we have to fist calculate marks obtained from the percentage of marks given.
