    Question

    Present age of ‘A’ is 25% more than that of ‘B’.

    If 15 years hence from now, ‘B’ will be 14 years younger than ‘A’, then find the sum of present ages of ‘A’ and ‘B’.
    A 106 years Correct Answer Incorrect Answer
    B 136 years Correct Answer Incorrect Answer
    C 120 years Correct Answer Incorrect Answer
    D 126 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let present age of ‘B’ be ‘x’ years Present age of ‘A’ = x × 1.25 = ‘1.25x’ years ATQ; (x + 15) + 14 = (1.25x + 15) Or, x + 29 = 1.25x + 15 Or, 14 = 0.25x Or, x = 56 So, present age of ‘B’ = 56 years And, present age of ‘A’ = 56 + 14 = 70 years Required sum = 56 + 70 = 126 years
