    There are three distinct numbers ‘a’, ‘b’ and

    ‘c’. If, a = 150, (a + b) = 450 and (c – b) = 60, then find the average of a, b and c.

    C 320 Correct Answer Incorrect Answer
    D 210 Correct Answer Incorrect Answer

    Solution

    Given, a = 150, (a + b) = 450 and (c – b) = 60 Therefore, b = 450 – 150 = 300 And, c = 300 + 60 = 360 Required average = (150 + 300 + 360)/3 = 270
