Question

help plzz it's s a one question that I tried alot ​

Answer 1

Answer:

Laspeyre's method

P=(∑P1Q0÷∑P0Q0)×100

Paasche's method

P=(∑P1Q1÷∑P0Q1) ×100

Fisher's method

P = √[ (∑P1Q0÷∑P0Q0) × (∑P1Q1÷∑P0Q1) ] ×100

Find the answer using these formulas, you will surely get it.

And am sorry I couldn't find you the answer but yeah u will surely get the answers with the formula.

Briefly on each Method

Laspeyre’s Method

Laspeyre was of the view that base year quantities must be chosen as weights. Therefore the formula is :

P=(∑P1Q0÷∑P0Q0)×100

Here, ∑P1Q0= Summation of prices of current year multiplied by quantities of the base year taken as weights and ∑P0Q0= Summation of, prices of base year multiplied by quantities of the base year taken as weights.

Paasche’s Method

Unlike the above mentioned, Paasche believed that the quantities of the current year must be taken as weights. Hence the formula:

P=(∑P1Q1÷∑P0Q1) ×100

Here, ∑P1Q1= Summation of, prices of current year multiplied by quantities of the current year taken as weights and ∑P0Q1= Summation of, prices of base year multiplied with quantities of the current year taken as weights.

Fisher’s Method

Fisher combined the best of both above-mentioned formulas which resulted in an ideal method. This method uses both current and base year quantities as weights as follows:

P = √[ (∑P1Q0÷∑P0Q0) × (∑P1Q1÷∑P0Q1) ] ×100

Fisher’s method uses views of both Laspeyres and Paasche. Hence it takes into account the prices and quantities of both years. Moreover, it is based on the concept of the geometric mean, which is considered as the best mean method.

NOTE: Index number of base year is generally assumed to be 100 if not given

Hope this is helpful
