|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?
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.
