    Problem with Calculating %age.

    I was going over a standardized test question involving percentages. The question is as follows
    In June a baseball team that had played 60 games had won 30% of its games played.Later after a winning streak the team raised the average to 50%.
    How many games must the teams have won in a row to attain this average ?
    The answer to this problem is 24.
    I cant manage to find out how they got 24 as the answer. Any suggestion would be appreciated. One reason i cant figure this out is because it doesnt state how many games they played later on ... I might be wrong. Any help would be appreciated.

    30% of 60 is 18.

    Therefore after 60 games they had won 18 and lost 42, to then go on a winning streak to achieve 50% to be wins then they require the 18 to increase to 42 (the same as the amount of losses). What is 42 take 18?

    Re: Problem with Calculating %age.

    I think i almost have it.. Though i am a bit confused at the part you said
    to then go on a winning streak to achieve 50% to be wins then they require the 18 to increase to 42 (the same as the amount of losses)
    Why do they need to increase 18 to 42 ? So far i know that they have lost 42 games. Could you elaborate on why they need the 42 ?

    because 42 wins & 42 losses is then 50% win. This should be clear...
