    Two numbers are in the ratio of 3 : 5. If each number is increased by 10, the ratio becomes 5 : 7. The numbers are

    A) 3, 5

    B) 7, 9

    C) 13, 22

    D) 15, 25

    Correct Answer: D

    Solution :

    [d] Let the numbers be 3x and 5x, Then, \[\frac{3x+10}{5x+10}=\frac{5}{7}\] \[\Rightarrow \]\[7\,(3x+10)=5\,(5x+10)\] \[\Rightarrow \]   \[4x=(70-50)=20\]\[\Rightarrow \]\[x=5\] \[\therefore \] The numbers are \[(3\times 5)\] and \[(5\times 5),\] i.e., 15 and 25.
