    Question

    Present age of ‘A’ is 40% more than that of ‘B’.

    If 11 years hence from now, ‘B’ will be 10 years younger than ‘A’, then find the sum of present ages of ‘A’ and ‘B’.
    A 60 years Correct Answer Incorrect Answer
    B 20 years Correct Answer Incorrect Answer
    C 50 years Correct Answer Incorrect Answer
    D 65 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 × 1.40 = ‘1.40x’ years ATQ; (x + 11) + 10 = (1.40x + 11) Or, x + 21 = 1.40x + 11 Or, 10 = 0.40x Or, x = 25 So, present age of ‘B’ = 25 years And, present age of ‘A’ = 25 + 10 = 35 years Required sum = 25 + 35 = 60 years
