Question
The ratio of Ankita and Sakshi 's ages will be 9:5 after
16 years. Currently, Ankita's present age is 180% more than Sakshi 's age four years ago. What is the average present age of Ankita and Sakshi?Solution
ATQ, Let age of Ankita and Sakshi after 16 years is 9a years and 5a years respectively. According to question; 9a β 16 = 2.80 Γ (5a β 20) Or, 9a β 16 = 14a β 56 Or, 5a = 40 So, a = 8 Desired Average = (14a β 32)/2 = 40 years
