Answer: 26.67%

### Explanation The correct answer is **B (26.67%)**, which represents the price return for an equal-weighted index. Here's the breakdown: 1. **Price Return Calculation for Each Security:** - **Security 1:** (18 / 20) - 1 = -10% - **Security 2:** (15 / 10) - 1 = 50% - **Security 3:** (21 / 15) - 1 = 40% 2. **Equal-Weighted Index Return:** The price return for an equal-weighted index is the average of the individual security returns: \[\frac{-10\% + 50\% + 40\%}{3} = 26.67\%\] **Why Not Other Options?** - **A (20%):** This is the price return for a price-weighted index, not an equal-weighted index. - **C (38.33%):** This represents the total return (including dividends) for an equal-weighted index, not the price return.
