Question
There is a fraction whose denominator is 5 more than its
numerator. If the numerator is increased by 10 and denominator is decreased by 4, the fraction will have its value 2. What is the fraction?Solution
Let the fraction be (x)/(y). As per the question, y = x  + 5, (x+10)/(x+5-4) = 2 Or  x + 10 = 2 x + 10 – 8 Or x = 8 Fraction = (8)/(8 + 5) = (8)/(13)
