|Teacher: ||You appeared for quizzes in 4 subjects, and your average marks in them were 84. |
|Student: ||How did I fare in English? |
|Teacher: ||Well, your average in English Language and English Literature is 79. |
|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 4 subjects = 4 × 84 = 336.
Total marks in 2 English subjects = 2 × 79 = 158.
Total marks in remaining 2 subjects = 336 − 158 = 178.
Average marks in remaining 2 subjects = 178 / 2 = 89.
