Using the following data, compute Fisher's Ideal Price Index Numbers for the current year:

129.60

The correct answer is Option (1) → 129.60

Fisher's Price Index Number ($P_{01}$):

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

$P_{01} = \sqrt{\frac{537}{416} \times \frac{622}{478}} \times 100$

$P_{01} = \sqrt{\frac{334014}{198848}} \times 100 \approx 129.60$
