Question
The present age of Ankit is the same as the age of Dev
before 8 years, while the age of Dev after 4 years is 12 years more than the present age of Mohit. If the ratio of the present age of Ankit and Mohit is 2:3, then find the sum of the ages of Ankit, Mohit, and Dev.Solution
ATQ, Let the present age of Ankit and Mohit be 2x and 3x respectively. 2x = Dev's age – 8 3x + 12 = Dev's age + 4 x = 8 Ankit’s age = 2 * 8 = 16 years Mohit’s age = 3 * 8 = 24 years Dev’s age = 32 years Required sum = 16 + 24 + 32 = 72 years
