Max. Marks(→) Students(↓)	Maths (150)	Chemistry (130)	Phsics (120)	Biology (100)	English (100)
Ankit	90	50	80	60	70
Amar	100	60	70	40	80

Rahul	80	75	65	90	90
Puneet	80	80	70	85	50
Pooja	70	75	50	80	40

What is the average marks obtained by all the six students in Chemistry?

1. 1. 86.66
2. 2. 76.66
3. 3. 66.66
4. 4. 60.00

Percentages of marks is given in table.
Average marks obtained by all students in chemistry
= Total obtained marks / Number of students
Total obtained marks = 130 * 0.5 + 0.6 * 130 * 0.6 * 130 * 0.75 * 130 * 0.8 * 130 * 0.75 * 130
=520
Average marks obtained by all students in chemistry = 520 / 6 = 86.66
So, option 1 is the correct answer.
