    Question

    The numerator of a fraction is 2 less than its denominator. If the numeratoris multiplied by 2 and the denominator is multiplied by 3, then the fractionbecomes 2/9. The fraction is,

    A.

    1/3 

    B.

    3/5

    C.

    5/7

    D.

    7/9

    Correct option is A

    Let the fraction be x/y, where the numerator x is 2 less than the denominator y.

    So, we write the equation:
    x = y - 2

    According to the problem, when the numerator is multiplied by 2 and the denominator by 3, the fraction becomes 2/9.
    2x3y=29\frac{2x}{3y} = \frac{2}{9}​​

    • Cross multiply:2x×9=2×3y2x \times 9 = 2 \times 3y

      18x=6y18x = 6y

      3x=y3x = y​​​​

    • Substituting x = y - 2 into 3x = y:3(y2)=y3(y - 2) = y

      3y6=y3y - 6 = y

      3yy=63y - y = 6

      2y=62y = 6

      y=3y = 3​​​​​​

      Finding x: x = y - 2 = 3 - 2 = 1

    So, the fraction is 1/3, which matches option (A) 1/3.
