If we add 1 to double the numerator of a fraction, we get the denominator. If we add 4 to both the numerator and the denominator, the fraction becomes 35. Find the fraction.
5/11
Numerator = y
Denominator = 2y + 1
Fraction=ND=y2y+1
As per the question,
y+42y+1+4=35
⇒5y+20=6y+15
⇒−y=−5
⇒y=5
Fraction= y2y+1=511
