    In 2003, Indian cricket team played 60 games and won 30% of the games played. After a phenomenal winning streak, this team raised its average to 50%. How many games did the team win in a row to attain this average?

    A)  36                         

    B)         24  

    C)  48                         

    D)         12

    Correct Answer: B

    Solution :

     Let the number of games won in a row be x. So  \[\frac{(30%\,\,of\,\,60)+x}{60+x}=\frac{50}{100}\] \[\Rightarrow \,36+2x=60+x\Rightarrow x=24\]
