Quizplus · Accepted Answer

The weighted aggregate price index for 2015 is calculated as (20% x 110) + (30% x 80) + (40% x 120) + (10% x 90) = 22 + 24 + 48 + 9 = 103. 
To calculate the index value with 2010 as the base year, we simply divide the 2015 index by the 2010 index and multiply by 100: (103/94) x 100 = 109.203. Therefore, the answer is C.
