    given order while ‘A’ = 20 and ‘B’ = 40, then find the value of ‘C’.

    C 85 Correct Answer Incorrect Answer
    D 95 Correct Answer Incorrect Answer

    Solution

    Given, A = 20
    And, B = 40
    Since, ‘A’, ‘B’ and ‘C’ are in proportion.
    So, (A/B) = (B/C)
    So, C = (40 × 40)/20 = 80
