What is the average of marks obtained by the all students in computer?
Answer & explanation
Correct answer: option 2
Sum of marks obtained in Computer = 90 + 90 + 80 + 95 + 85 + 100 = 540
Total students = 6
Average marks = \(\frac{\text{sum of observations}} {no. of observations}\) = \(\frac{540}{6}\) = 90
