Answer:
51 games
Explanation:
Each team plays 160 games
After playing half their games (1/2 of 160 = 0.5 * 160 = 80), A has won 60 and B had won 49
In 80 games, A won 60 and B won 49
Remaining games = 160 - 80 = 80
In the remaining 80 games, A will win 1/2 (80 * 1/2 = 40), making their total 60 + 40 = 100. B therefore must win the difference between the games they need to have won to tie A (100) and the games they have currently won (49) = 100-49=51 games
