    Present age of β€˜A’ is 40% more than that of β€˜B’.

    If 11 years hence from now, β€˜B’ will be 5 years younger than β€˜A’, then find the sum of present ages of β€˜A’ and β€˜B’.
    A 30 years Correct Answer Incorrect Answer
    B 32 years Correct Answer Incorrect Answer
    C 33 years Correct Answer Incorrect Answer
    D 35 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let present age of β€˜B’ be β€˜x’ years Present age of β€˜A’ = x Γ— 1.40 = β€˜1.40x’ years ATQ; (x + 11) + 5 = (1.40x + 11) Or, x + 16 = 1.40x + 11 Or, 5 = 0.40x Or, x = 12.5 So, present age of β€˜B’ = 12.5 years And, present age of β€˜A’ = 12.5 + 5 = 17.5 years Required sum = 12.5 + 17.5 = 30 years
