Given that $∑p_0q_0= 700, ∑p_0q_1=1450, ∑p_1q_0=855$ and $∑p_1q_1=1300.$ Where subscripts 0 and 1 are used for base year and current year respectively. The Laspeyer's price index number is :

122.14

The correct answer is Option (4) → 122.14

The Laspeyres Price Index is,

$P_L=\frac{∑(p_1q_0)}{∑p_0q_0}×100$

$=\frac{855}{700}×100$

$=122.14$
