    Question

    Two numbers are in the ratio 9:7. If 14 is subtracted from each, the ratio becomes 7:5. Then the numbers are

    A.

    39 and 63

    B.

    28 and 45

    C.

    63 and 49

    D.

    60 and 49

    Correct option is C

    Given:

    1. Two numbers are in the ratio 9:7.

    2. After subtracting 14 from each number, the ratio becomes 7:5

    Formula Used:

    1. Represent the numbers as 9x and 7x based on the given ratio.

    2. After subtracting 14 from each:

    9x147x14=75\frac{9x - 14}{7x - 14} = \frac{7}{5}

    3. Solve for x to find the numbers:

    9x14=75(7x14)9x - 14 = \frac{7}{5} (7x - 14)

    Solution:

    1. Expand the equation:

    9x14=75(7x14)9x - 14 = \frac{7}{5} (7x - 14)

    Multiply through by 5 to eliminate the fraction:

    5(9x - 14) = 7(7x - 14)

    45x - 70 = 49x - 98

    2. Simplify the equation:

    45x - 49x = -98 + 70

    -4x = -28

    x = 7

    3. Substitute x = 7 into 9x and 7x to find the numbers:

    9x=97=639x = 9 \cdot 7 = 63

    7x=77=497x = 7 \cdot 7 = 49

    Final Answer:

    The numbers are **63** and **49**.
