Let C be correct answers, W be wrong answers. C + W = 34. Score equation: 2.5(C) - 1(W) = 67. Substitute W = 34 - C: 2.5C - (34 - C) = 67 -> 3.5C = 101. C = 101 / 3.5 ≈ 28.85. Since correct answers must be whole numbers, the scenario mathematically cannot exist. Source Reference: "hujjaj prep" - Administrative and logistic arrangements
