Two commodities have price relatives of 120 and 150, with weights 4 and 6 respectively. What is their weighted average of price relatives?

Correct answer: C. 138

  • A. 132
  • B. 136
  • C. 138
  • D. 142

Explanation

The weighted average is (120 × 4 + 150 × 6) ÷ (4 + 6) = 138. The larger weight assigned to the second commodity pulls the result closer to 150.
