Question
If 25 is added to the numerator of a fraction and its
denominator is multiplied by 10, the value of the fraction increases by 35%. What is the numerator of the original fraction?Solution
Let the original fraction be = x/y According to the question, (x + 25)/(y x 10) = (x/y) x (135/100) (x + 25)/10y = (27x/20y) Or, 270xy = 20xy + 500y Or, 250xy = 500y Or, x = 2 So, numerator of the original fraction = 2
