    If 20% of \[x=25%\] of y, then \[x:y\] is equal to:

    A)  \[1:2\]             

    B)  \[5:4\]

    C)  \[5:1\]                          

    D)  \[10:1\]

    Correct Answer: B

    Solution :

     20% of \[x\]=25% of y \[\frac{20x}{100}=\frac{25y}{100}\]                \[\frac{x}{y}=\frac{25}{100}\bullet \frac{100}{200}=\frac{5}{4}\] \[x:y=5:4\]
