    If X gives Y seven apples, then Y will then have five times as many as X would have, however, if Y give X seven apples, then both X and Y will have the same number of apples. How many apples do X currently have?

    Let no of apples with x as n1
    Let no of apples with y as n2

    Then according to first condition
    n2+7 = 5* (n1-7)-----------------------(1)

    From the second condition we have
    n2-7=n1+7-----------------------------(2)

    Thus solving (1) and (2) we have
    n1=14 n2=28

    Re: Think and Answer

    Call No. of apple of Y is n1
    Call No. of apple of X is n2
    We have :

    n1 + 5 = 5*(n2 - 5) => n1 = 5*n2 - 30 (1)

    on the other hand :

    n1 - 7 = n2 + 7 => n1 = n2 + 14 (2)

    From (1) and (2), we have

    n1 = 25
    n2 = 11

    I'm sure this is the correct answer.

    14 & 28 is not the correct answer.
