No answer key was printed for this question.
Explanation
Let the attendance on the three days be 3x, 6x and 11x respectively. Then, total charges collected = ₹(12 × 3x + 9.5 × 6x + 4 × 11x) = ₹(36x + 57x + 44x) = ₹137x. Total attendance on 3 days = (3x + 6x + 11x) = 20x. Average charge per person = $₹\frac{137x}{20x} = ₹6.85$.
