Teacher: You appeared for quizzes in 10 subjects, and your average marks in them were 80.
Student: How did I fare in English?
Teacher: Well, your average in English Language and English Literature is 44.
Student: So, how was my performance in the remaining subjects?
Teacher: I am sure you can figure that out for yourself.

Can you help the student find his average marks in the remaining subjects?

Answer: 89

Solution:

Total marks in 10 subjects = 10 × 80 = 800.

Total marks in 2 English subjects = 2 × 44 = 88.

Total marks in remaining 8 subjects = 800 − 88 = 712.

Average marks in remaining 8 subjects = 712 / 8 = 89.

Food for thought:

What is another term for "average" in statistics? Is it "mean", "median" or "mode"?
