Show answer & explanation
Correct answer: D
Concept: The overall average marks across several subjects is the sum of each subject's given average marks divided by the number of subjects (a simple, equally weighted mean of the individual averages).
From the 2009 row of the table, the average (Ave.) marks are: English = 56, Maths = 68, Science = 68, Social Science = 48.
Add the four average marks: 56 + 68 + 68 + 48 = 240.
Divide the total by the number of subjects: 240 ÷ 4 = 60.
Cross-check: This value lies between the lowest (48) and the highest (68) of the four subject averages, as any average must. Re-adding step by step — 56 + 68 = 124, 124 + 68 = 192, 192 + 48 = 240, and 240 ÷ 4 = 60 — confirms the result.
So the overall average of marks in the four subjects for 2009 is 60.
