    Three years ago, Ritu was twice as old as Rajni, and

    A 27 years Correct Answer Incorrect Answer

    D 12 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let Ritu's current age be x and Rajni's current age be y. Three years ago: x−3=2(y−3) (Ritu was twice Rajni's age) Currently: x+y=36 (Their total age is 36) Solve the equations: Ritu's current age, x = 23 Ritu's age 4 years from now = 23+4=27 years
