Correct answer: B
Concept
Revenue from a flat per-head ticket charge = (charge per person) × (number of people who visited). For a Data Interpretation line graph, the number of people is read directly off the correct series at the labelled point — here the upper line, "(Boys + Girls)", which is the TOTAL number of people.
Applying it to park E
Identify the value to multiply: the charge applies to every person (Boys + Girls), so use the total-people series, not the girls-only series.
Read park E on the "(Boys + Girls)" line: the marker sits at 54 people.
Apply the revenue rule: total revenue = 24 × 54.
Cross-check
Cross-check the product: 24 × 54 = 24 × 50 + 24 × 4 = 1200 + 96 = 1296. So park E collects Rs. 1296.
