I: The ratio between the present ages of A and B is 9:13 respectively and B is 8 years elder than A. Quantity II: 25 years In the question, two quantities I and II are given. You have to solve both the quantities to establish the correct relation between Quantity-I and Quantity-II and choose the correct option.Solution
Quantity I: Let the present age of A and B be 9x and 13x respectively. According to question, => 13x – 9x = 8 => x = 2 A’s age after 3 years = (9 x 2) + 3 = 21 years Quantity II: 25 years Therefore, Quantity I < Quantity II
