Here, base year is 2014 and current year is 2015.
∴ P0 = Price in 2014,
q0 = Quantity in 2014,
P1 = Price in 2015 and
q1 = Quantity in 2015
The table for calculation is prepared as follows:
Laspeyre’s index number:
\(I_L= \frac{\sum {p_1\,q_0}}{\sum {p_0\,q_0}} \times 100\)
\(=\frac{4085}{3730} \times 100\)
= 109.52
Paasche’s index number:
\(I_p= \frac{\sum {p_1\,q_1}}{\sum {p_0\,q_1}} \times 100\)
\(=\frac{5475}{4964}\times 100\)
= 110.29
Fisher’s index number:
