Question
The ratio of the present ages of Ginni and Binni is 7:4
respectively. Ginni is ‘n’ years older than Binni. If after 2 years, the ratio of the ages of Binni to Ginni is 2:3, then find the value of √(n+6).Solution
Let the present ages of Ginni and Binni be 7x and 4x respectively. Here, n = 7x – 4x = 3x According to the question, => (7x + 2)/(4x + 2) = 3/2 => x = 1 Now, n = 3x = 3 Required value = √(n+6) = √(3+6) = √9 = 3
