To calculate the weighted aggregate price index, we need to use the formula:
(W1 x P1 + W2 x P2 + W3 x P3)/(W1 + W2 + W3) x 100
Substituting the given values, we get:
(10 x 12 + 20 x 8 + 30 x 6)/(10 + 20 + 30) x 100
= (120 + 160 + 180)/60 x 100
= 163.768
Therefore, the weighted aggregate price index for 2010 is 163.768.
