    The current age ratio of Riya to Simran is 5:2. In eight

    years, Riya’s age will be twice Simran’s age at that time. What is Riya’s present age?
    A 40 yrs Correct Answer Incorrect Answer
    B 32 yrs Correct Answer Incorrect Answer
    C 48 yrs Correct Answer Incorrect Answer
    D 55 yrs Correct Answer Incorrect Answer

    Solution

    ATQ;
    Let the present age of ‘Simran’ = ‘x’ years
    Present age of ‘Riya’ = ‘5x’ years
    ATQ;
    5x + 8 = 2 × (x + 8)
    Or, 5x + 8 = 2x + 16
    Or, 3x = 8
    Or, x = 8
    So, present age of ‘Riya’ = 5 × x = 5 × 8 = 40 years
