The price index is calculated as
- \(\frac{\text{weighted price}}{\text{current price}}\) x \(\frac{100}{1}\)
- \(\frac{\text{base year price}}{\text{current price}}\) x \(\frac{100}{1}\)
- \(\frac{\text{current price}}{\text{weighted price}}\) x \(\frac{100}{1}\)
-
\(\frac{\text{current price}}{\text{base year price}}\) x \(\frac{100}{1}\)
