Question
Five years ago from now, ratio of ages of Aman and
Bharat was 3:5, respectively. If 5 years hence from now, ratio of their ages will be 5:7, then find the present age of Bharat.Solution
Let age of Aman and Bharat, 5 years ago from now was '3x' years and '5x' years, respectively ATQ; {(3x + 10)/(5x + 10)} = (5/7) Or, 21x + 70 = 25x + 50 Or, 4x = 20 Or, x = 5 So, present age of Bharat = 5x + 5 = 5 X 5 + 5 = 30 years Hence, option c.
