Let the team played 100 games.
Now 80% it played already i.e. 80 games and out of these it won only 50% => 40.
Now 20% remaining will be 20 and out of these only 60% won i.e only 12 games.
Total won = 52
won percentage = 52/100 = 52%.
Col B also 52%.
Both same.
C.

Explanation
Choose a smart number for the total number of games; for a percent problem, 100 is a good number to pick. If the total number of games for the season is 100 and the team played 80% of them by July, then the team played (100)(0.8) = 80 games. The team won 50% of these games, or (80)(0.5) = 40 games.
Next, the team won 60% of its remaining games. As there were 100 total games and the team has played 80 of them, there are 20 games left to play. Of these, the team won 60%, or (20)(0.6) = 12 games.
Therefore, the team has won a total of 40 + 12 = 52 games out of 100, or 52% of its total games. The two quantities are equal.
