The original ratio cannot be determined

Solution:

Let the numerator be x and denominator be y

Original\ fraction = \frac{x}{y}

When 7 is added to the numerator and denominator of the fraction the new ratio of numerator and denominator is 13 : 19

Then,

New\ fraction = \frac{x + 7}{y + 7}

Ratio = 13 : 19

Therefore,

\frac{x+7}{y+7} = \frac{13}{19}

x and y are different variable ,so original fraction cannot be determined
