If the numerator of a fraction is increased by 15% and denominator is decreased by 20%, then the fraction, so obtained, is $$\frac{17}{65}$$ What is the original fraction?
Let the numerator of the fraction = $$x$$
Denominator of the fraction = $$y$$
Numerator when increased by 15% =Â $$\frac{115}{100}x$$
Denominator when decreased by 20% = $$\frac{80}{100}y$$
Given, new fraction = $$\frac{17}{65}$$
$$=$$> Â $$\frac{\frac{115}{100}x}{\frac{80}{100}y}=\frac{17}{65}$$
$$=$$> Â $$\frac{115x}{80y}=\frac{17}{65}$$
$$=$$> Â $$\frac{x}{y}=\frac{17\times80}{65\times115}$$
$$=$$> Â $$\frac{x}{y}=\frac{272}{1495}$$
$$\therefore$$The original fraction $$=\frac{x}{y}=\frac{272}{1495}$$
Hence, the correct answer is Option A
