Construct index number of price from the following date by using Fisher's method:

125.09

The correct answer is Option (2) → 125.09

Fisher's Method:

$P_{01} = \sqrt{\frac{\sum p_1q_0}{\sum p_0q_0} \times \frac{\sum p_1q_1}{\sum p_0q_1}} \times 100$

$= \sqrt{\frac{200}{160} \times \frac{134}{107}} \times 100= \sqrt{1.565} \times 100$

$=1.2509\times 100  = 125.09$
