    If 10% of m is the same as 20% of n, then m : n is equal to

    A) 2: 1                  

    B) 1: 2     

    C) 1: 10                            

    D) 1: 20

    Correct Answer: A

    Solution :

    \[\therefore \] 10% of \[m=20%\text{ of }n\] \[\Rightarrow \]   \[\frac{10m}{100}=\frac{20n}{100}\] \[\Rightarrow \]   \[\frac{m}{10}=\frac{n}{5}\] \[\Rightarrow \]   \[\frac{m}{n}=\frac{2}{1}\] \[\Rightarrow \]   \[m:n=2:1\]
