- The charges for the show over three days are Rs10, Rs5, and Rs2 respectively.
- The attendance ratio over these days is 15:2:3.
- To find the average charge per person, calculate total revenue and divide by total attendance.
- Assume a common multiplier for attendance:
- Day 1: 15x people
- Day 2: 2x people
- Day 3: 3x people
- Total attendance: \(15x + 2x + 3x = 20x\)
- Total revenue:
- Day 1: \(15x \times Rs10 = Rs150x\)
- Day 2: \(2x \times Rs5 = Rs10x\)
- Day 3: \(3x \times Rs2 = Rs6x\)
- Total revenue over three days: \(Rs150x + Rs10x + Rs6x = Rs166x\)
- Average charge per person: \(\frac{Rs166x}{20x} = Rs8.30\)

✅ **Option 1: Rs8.30**
