    If the numerator of a fraction is increased by 250% and the denominator is increased by 400%, the resultant fraction is\[\frac{7}{19}.\]What is the original fraction?

    A)  \[\frac{10}{19}\]          

    B)  \[\frac{5}{16}\]

    C)  \[\frac{11}{12}\]                                  

    D)  \[\frac{5}{13}\]

    Correct Answer: A

    Solution :

    Let the original fraction be \[\frac{x}{y}\] According to the question, \[\frac{\frac{x\times 350}{100}}{\frac{y\times 500}{100}}=\frac{7}{19}\]\[\Rightarrow \]\[\frac{x}{y}=\frac{7}{19}\times \frac{5}{3.5};\]\[\frac{x}{y}=\frac{10}{19}\]
