    Present ages of 'A' and 'B' are in the ratio 6:5,

    respectively. Present age of 'C' is 50% more than 'B'. If the difference between present ages of 'C' and 'A' is 12 years, then find the present age of 'B'.

    B 36 years Correct Answer Incorrect Answer
    C 40 years Correct Answer Incorrect Answer
    D 45 years Correct Answer Incorrect Answer
    E 32 years Correct Answer Incorrect Answer

    Solution

    Let the present age of 'A' be '6x' years So, present age of 'B' = 6x Ă— (5/6) = '5x' years So, present age of 'C' = 5x Ă— 1.5 = '7.5x' years ATQ; 7.5x - 6x = 12 Or, 1.5x = 12 So, x = 8 So, present age of 'B' = 5x = 8 Ă— 5 = 40 years
