    Question

    If we add 1 to the numerator and subtract 1 from the denominator of a given fraction, it becomes 1 . It becomes 2/3 if 1 is added to the denominator of the given fraction while the numerator is left unchanged. The fraction originally given is:

    A.

    58\frac58

    B.

    68\frac68

    C.

    18\frac18

    D.

    38\frac38

    Correct option is B

    Given:

    xy\frac{x}{y}​​

    If 1 is added to the numerator and 1 is subtracted from the denominator, the fraction becomes 1

    x+1y1=1\frac{x+1}{y-1} = 1

    If 1 is added to the denominator, the fraction becomes 23\frac{2}{3}​​

    xy+1=23\frac{x}{y+1} = \frac{2}{3}

    Solution:

    3(y - 2) = 2y + 2

    3y - 6 = 2y + 2

    y - 6 = 2

    y = 8

    Now substitute y = 8 into

    x = y - 2

    x = 8 - 2 = 6
