Question
The current average age of three friends, Aravi, Bipasa,
and Chinu, is 24 years. The ratio of Chinu's and Diksha's present ages is 4:5, and Bipasa's current age is 45% less than Diksha's. To determine Diksha's present age, we're given that Chinu's age 4 years from now will be twice Aravi's current age.Solution
ATQ, Let the present age ‘Chinu’ and ‘Diksha’ be ‘4c’ years and ‘5c’ years, respectively. So, present age of ‘Bipasa’ = 5c × 0.55 = ‘2.75c’ years Present age of ‘Aravi’ = (4c + 4)/2 = (2c + 2) years According to question: 2c + 2 + 2.75c + 4c = 24 × 3 Or, 8.75c = 70 c = 8 Present age of Diksha = 5 × 8 = 40 years
