    The sum of 5% of a number and 4% of other number is \[\frac{2}{3}\]of the sum of 6% of the first number and 8% of second. The ratio of the first number to the second is

    A)   2 : 3   

    B)   3 : 2

    C)   3 : 4               

    D)   4 : 3

    Correct Answer: D

    Solution :

    Let the first number = x and the second number = y According to question, 5% of x + 4% of \[y=\frac{2}{3}\](6% of x + 8% of y) \[\Rightarrow \]   \[3(5x+4y)=2(6x+8y)\] \[\Rightarrow \]\[15x+12y=12y=12x+16y\Rightarrow 3x=4y\] \[\Rightarrow \]               \[\,\frac{x}{y}=\frac{4}{3}\]
