falling short of the passing mark by 42 marks. On the other hand, Vijay achieved 41% of the total marks, surpassing the passing threshold by 36 marks. Determine the passing marks for this examination.Solution
Let the maximum marks of the examination = x So according to question: 0.28x + 42 = 0.41x – 36 0.13x = 78, x = 600 So the passing marks = 600 × 0.28 + 42 = 168 + 42 = 210 Hence, option c.
