    The sum of two numbers is 137 and their difference is 43. Algebraic representation of the situation can be:

    A) \[x-y=137,\,\,x+y=180\]

    B) \[2(x+y)=137,\,(x-y)=43\]

    C) \[x+y=137,\,\,x-y=43\]

    D) \[x+y=43,\,\,x-y=137\]

    Correct Answer: C

    Solution :

    [c] Let the two numbers be x and y, where \[x>y\].
    \[\therefore \]  According to the question,                             
    \[x+y=137\] and \[x-y=43\]
