Weighted Index Numbers

If Laspeyre’s price index is $289$ and Paasche’s price index is $225$ then Fisher’s ideal index is

The consumer price index in the year $2000$ increases by$80\%$ as compared to the base $1990$. A person I $1990$ getting $Rs. 80,000$ per annum should now get:

The consumer price index numbers for 1981 and 1982 to the base 1974 are$360$ and $400$ respectively. The consumer price index for 1981 to the base 1982 is

If Laspeyre’s price index is $625$ and Paasche’s price index is $576$ then Fisher’s ideal index is

The price relatives and weights of some products are given below.

Find the value of $x$ if the index for the set is $115$.

The price index of a product A in $2021$ compared to $2015$ is $120$. If the price of the product in $2015$ was $₹1000$, find the price of the product in $2021$ in $₹$.

Calculate the weighted index number of the following data using the price relative method:

List the uses of weighted arithmetic mean in index numbers

State the difference between weighted and unweighted index numbers

Explain briefly about weighted index number.

The price relatives and weights of some products are given below.

$\begin{array}{|ccccc|}\hline Products& A& B& C& D\\ Price relatives& 120& 110& 105& 115\\ Weights& x+1& x-1& x-2& x+2\\ \hline\end{array}$

Write the formula used for finding Index. Find the value of $x$ if the index for the set is $115$.
