C Correct answer
Explanation

Initially: 60 games played with 30% wins = 18 wins. Let x be consecutive wins needed. Total wins = 18 + x. Total games = 60 + x. We want (18+x)/(60+x) = 50% = 0.5. Solving: 18 + x = 0.5(60 + x) = 30 + 0.5x. So 0.5x = 12, and x = 24. The team needs to win 24 games in a row to reach 50% overall.
