    The difference of two numbers is 20% of the larger number. If the smaller number is 20, the larger number is

    A)  25

    B)  45      

    C)  50

    D)  80

    Correct Answer: A

    Solution :

    Let the larger number be x. According to question, \[x-20=20%\]of \[x\] \[\Rightarrow \]\[x-20=\frac{x}{5}\]\[\Rightarrow \]\[x-\frac{x}{5}=20\] \[\Rightarrow \]   \[5x-x=20\times 5\] \[\Rightarrow \]\[4x=20\times 5\] \[\therefore \]                  \[x=5\times 5=25\]
