The line chart given below shows the average marks obtained by each student of 6 classes C1, C2, C3, C4, C5 and C6 in a school.

Average marks of each student of which class is 100% of the average marks of each student of class C2?
Show answer & explanation
Correct answer: B
Explanation
C1 = 86, C2 = 89, C3 = 74, C4 = 89, C5 = 73, C6 = 95
If A = 100% of B ⇒ A = B
C2 = 89
The one whose value is 89 ⇒ C4 = 89
