C Correct answer
Explanation

C is correct. Initially: 60 games × 30% = 18 wins. After x consecutive wins, (18+x)/(60+x) = 50%. Solving: 18+x = 30+0.5x → 0.5x = 12 → x = 24. Verify: (18+24)/(60+24) = 42/84 = 50%. Option A (12) gives 30/72 ≈ 41.7%, B (20) gives 38/80 ≈ 47.5%, and D (40) gives 58/100 = 58%.
