Levana,

You have made a mistake while calculating Weights(W). You have calculated W by multiplying $P_0$ and $P_1$. However, W is calculated by multiplying base year prices $P_0$ with the base year quantity $Q_0$. You have also committed a mistake while calculating R corresponding to commodity E. R is calculated as $\frac{P_1}{P_0} \times 100$. In case of commodity E you have calculated the value of R by taking $\frac{P_0}{P_1} \times 100$.
