Question
The ratio of the present ages of Ginni and Binni is 9:4
respectively. Ginni is ‘n’ years older than Binni. If after 5 years, the ratio of the ages of Binni to Ginni is 1:2, then find the value of √(n+11).Solution
Let the present ages of Ginni and Binni be 9x and 4x respectively. Here, n = 9x – 4x = 5x According to the question, => (9x + 5)/(4x + 5) = 2/1 => x = 5 Now, n = 5x = 25 Required value = √(n+11) = √(25+11) = √36 = 6
