Construct index number of price from the following date by using Marshall-Edgeworth method:

125.09

The correct answer is Option (4) → 125.09

Marshall-Edgeworth Method:

$P_{01} = \frac{\sum p_1(q_0 + q_1)}{\sum p_0(q_0 + q_1)} \times 100 = \frac{\sum p_1q_0 + \sum p_1q_1}{\sum p_0q_0 + \sum p_0q_1} \times 100$

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

$= \frac{334}{267} \times 100 = 125.09$
