Question
The ratio of the present ages of Ginni and Binni is 8:3
respectively. Ginni is ‘n’ years older than Binni. If after 4 years, the ratio of the ages of Binni to Ginni is 1:2, then find the value of √(n+6).Solution
Let the present ages of Ginni and Binni be 8x and 3x respectively. Here, n = 8x – 3x = 5x According to the question, => (8x + 4)/(3x + 4) = 2/1 => x = 2 Now, n = 5x = 10 Required value = √(n+6) = √(10+6) = √16 = 4
