    Question

    ‘m’ varies directly with ‘n’. When m = 40, the

    value of ‘n’ is 10% more than ‘m’. Find the value of ‘m’ when n = 77.
    A 70 Correct Answer Incorrect Answer
    B 90 Correct Answer Incorrect Answer
    C 55 Correct Answer Incorrect Answer
    D 25 Correct Answer Incorrect Answer

    Solution


    ATQ,

    M = k × n (Where ‘k’ is proportionality constant)

    ATQ;

    40 = k × (1.1 × 40)

    Or, k = (10/11)

    So, required value = (10/11) × 77 = 70
