【正确答案】 A

【答案解析】Cost of basket in base period =24 × 15.60 + 43 × 13.90 + 5 × 19.40 + 20 × 12.40 = 1317.10. Cost of basket in current period =24 × 16.40 + 43 × 14.60 + 5 × 17.60 +20 × 12.80 = 1365.40. CPI = cost of basket in current period/cost of basket in base period × 100 = 1365.4/1317.1 × 100 = 103.67.
