    Question

    If (2a + b)/(3b - 2b) = 13/2 then 'b' is what percent of

    'a'?
    A 120% Correct Answer Incorrect Answer
    B 125% Correct Answer Incorrect Answer
    C 100% Correct Answer Incorrect Answer
    D 150% Correct Answer Incorrect Answer

    Solution

    (2a + b)/(3b - 2b) = 13/2┬а So, 2 X (2a + b) = 13 X (3a - 2b) Or, 4a + 2b = 39a - 26b Or, 35a = 28b Or, (a/b) = (28/35) = (4/5) Let 'a' = 4k and 'b' = 5k Required percent = (5k/4k) X 100 = 125%
