Supposing that there were 40 students in science in the year 2009. How much total of marks did they receive combined together?
- A.
2800
- B.
2720
- C.
2560
- D.
3000
Show answer & explanation
Correct answer: B
Concept: The total marks scored by a group of students in a subject equal the number of students multiplied by the average marks per student for that subject and year, since the average is defined as total marks divided by the number of students.
Application: From the table, the average marks in Science for 2009 is 68. With 40 students, total marks = 40 × 68 = 2720.
Cross-check: This total is comfortably below the theoretical maximum of 40 × 97 = 3880 (using the highest score of 97 for Science 2009), confirming the figure is a realistic combined total consistent with the given average of 68.
