Explanation

Let initial costs be 16k and 23k. After changes: 16k(1.1) : (23k + 477) = 11 : 20. So 17.6k / (23k + 477) = 11/20, 352k = 253k + 5391, 99k = 5391, k = 54.45. Initial cost of second article = 23k = 23 × 54.45 ≈ 1252.35. However, checking option B (1219): 1219/54 ≈ 22.57, not exactly 23. The math suggests the exact answer might involve fractional values.
