Question : The denominator of a fraction is 4 more than twice the numerator. When the numerator is increased by 3 and the denominator is decreased by 3, the fraction becomes $\frac{2}{3}$. What is the difference between the denominator and numerator of the original fraction?
Option 1: 13
Option 2: 10
Option 3: 12
Option 4: 11
Correct Answer: 11
Solution : Let the original fraction be $\frac{x}{y}$ According to the question, $y = 2x + 4$ .............(1) When 3 is added to the numerator and 3 is subtracted from the denominator the fraction becomes $\frac{2}{3}$ ⇒ new fraction = $\frac{x + 3}{y – 3} = \frac{2}{3}$
