      "text": "Could you estimate the number of burgers a McDonald's outlet sells in a day?",
      "context": "This is an average McDonald's outlet, not in a specific location like an airport. Only considering in-restaurant purchases.",
      "referenceAnswer": "To estimate the number of burgers a McDonald's outlet sells in a day, I'll use a structured approach:\n\n1. Restaurant capacity: An average McDonald's has about 50 seats\n2. Operating hours: Typically open from 10 am to 10 pm (12 hours)\n3. Peak vs. non-peak consumption patterns:\n   - Peak hours (12-2pm, 6-8pm): 80-90% occupancy\n   - Regular hours: 30-40% occupancy\n4. Average meal time: 20-30 minutes\n5. Burger consumption: About 70% of customers order a burger\n\nCalculation:\n- Peak hours (4 hours): 50 seats × 0.85 occupancy × (4 hours × 60 min / 25 min per customer) × 0.7 burger rate ≈ 714 burgers\n- Regular hours (8 hours): 50 seats × 0.35 occupancy × (8 hours × 60 min / 25 min per customer) × 0.7 burger rate ≈ 588 burgers\n\nTotal: Approximately 1,300 burgers per day.",

      "text": "Estimate the number of smartphones sold in India annually.",
      "context": "Consider the overall market size and demographic factors that influence smartphone purchases in India.",
      "companies": ["general", "e-commerce", "tech"],
      "referenceAnswer": "To estimate the number of smartphones sold in India annually:\n\n1. Population: India has approximately 1.4 billion people\n2. Household formation: Average 4-5 people per household, so around 300 million households\n3. Smartphone penetration: About 60-65% of the population has access to smartphones\n4. Replacement cycle: Average user replaces their smartphone every 2-3 years\n5. New adopters: Market is still growing with first-time buyers\n\nCalculation:\n- Existing users: 1.4 billion × 0.65 ≈ 900 million smartphone users\n- Annual replacement: 900 million ÷ 2.5 years ≈ 360 million smartphones\n- New adopters: Penetration increasing by ~5% annually = 70 million new users\n\nTotal annual smartphone sales: Approximately 430 million units per year.",
