Three years ago, Ritu was twice as old as Rajni, and currently, the total of their ages is 36 years. What will Ritu's age be four years from now?
ATQ, Let Ritu's present age be represented as x, and Rajni's age as 36 - x. Three years ago, Ritu's age was x - 3, and Rajni's age was 36 - x - 3. In the future, after 4 years, Ritu's age will be x + 4. Given that three years ago, Rajni's age was twice Ritu's age, we can set up the equation: 36 - x - 3 = 2(x - 3). Solving for x: 36 - x = 2x - 6, 3x = 42, x = 14 years. So, Ritu's age after 4 years will be: x + 4 = 14 + 4 = 18 years.
