    Question

    Three years from now, Aman's age

    will be 80% greater than what it was five years ago. The average of Aman's current age and Bishnu's current age is 21 years. What will be the ratio of their ages one year from now?
    A 4:7 Correct Answer Incorrect Answer
    B 6:5 Correct Answer Incorrect Answer
    C 7:5 Correct Answer Incorrect Answer
    D 9:5 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the present age of ‘Aman’ = ‘x’ years According to the question, (x + 3) = 1.8 × (x – 5) Or, x + 3 = 1.8x – 9 Or, x = 12 ÷ 0.8 = 15 Sum of present ages of ‘Aman’ and ‘Bishnu’ = 21 × 2 = 42 years So, present age of ‘Bishnu’ = 42 – 15 = 27 years So, required ratio = (15 + 1):(27 + 1) = 16:28 = 4:7
