Solution

Let the original fraction = $\frac{x}{y}

Numerator after 350% increase = $x + \frac{350}{100} \times x = 4.5x$

Denominator after 300 % increase = $y + \frac{300}{100} \times y = 4y$

Acc to ques,

=> $\frac{4.5x}{4y} = \frac{9}{22}$

=> $\frac{x}{y} = \frac{9}{22} \times \frac{4}{4.5}$

=> $\frac{x}{y} = \frac{4}{11}$
