In june a baseball team that played 60 games had won 30% of its game played. After a phenomenal winning streak this team raised its average to 50% .How many games must the team have won in a row to attain this average?

A. 12 B. 20 C. 24 D. 30

• total games won by the team = 18
  so as the team wins continuous matches and raises winning % to 50
  therefore, ((18+x)/(60+x))*100 = 50
  i.e. (18+x)/(60+x) = 1/2
  which gives us the value of x = 24....
  so , team has to play 24 more games to attain avg. of 50 %

• 60 games - 30% win = 18 games
  60 + x games - 50% win = 18+ x
  (60+x)*50/100 = 18+ x
  (60 + x)* 1/2 =18+ x
  (60+x) = 36 + 2x
  x=60-36 = 24 Ans

• Now given the baseball team had played 60 games.
  and won 30%
  then 60*(30/10)=18
  now after a phenomenal winning is the average to 50%
  now team players the y, ok the increases the 50% then
  
  
  60+y)*50/100=18+y
  (60+y)/2=18+y
  60+y=36+2y
  24=y
  Ans is y=24
