Compute the weighted aggregative index number for the following data:

137.84

The correct answer is Option (3) → 137.84

The weighted aggregative price index is given by:

$P_{01} = \frac{\sum p_1 W}{\sum p_0 W} \times 100$

Calculation Table:

Apply the formula:

$P_{01} = \frac{510}{370} \times 100$

$P_{01} \approx 1.378378 \times 100$

$P_{01} = 137.84$
