    In a class, the number of boys is more than the number of girls by 12% of the total students. What is the ratio of number of boys to that of girls?

    A) 11 : 14             

    B) 14 : 11

    C) 28 : 25             

    D) 25 : 28

    Correct Answer: B

    Solution :

    Let the number of boys \[=x\] and the number of girls \[=y\] By given condition, \[x-y=\frac{(x+y)\times 12}{100}\] \[\Rightarrow \]   \[25x-25y=3x+3y\] \[\Rightarrow \]   \[22x=28y\] \[\Rightarrow \]   \[x:y=14:11\]
