Answer / suryaveer
Total game played= 60
%won =30%
Total won= 60*30/100 i.e. 18
now team plays x games and win all of those to increase the
average to 50%.
So,
(60+x)*50/100=18+x
(60+x)/2=18+x
60+x=36+2x
24=x
So the final answer is 24.

Answer / hemant
30% of 60 games = 18 games
Let
x = number of games won during the winning streak
(18 + x)/(60 + x) = 0.50
18 + x = 0.50(60 + x)
18 + x = 30 + 0.50x
0.50x = 12
x = 24
