    Question

    β€˜a’ is directly proportional to β€˜b’. If at a=30,

    the value of β€˜b’ is 20% greater than β€˜a’, then find the value of β€˜a’ when b=54.
    A 45 Correct Answer Incorrect Answer
    B 53 Correct Answer Incorrect Answer
    C 77 Correct Answer Incorrect Answer
    D 95 Correct Answer Incorrect Answer

    Solution

    ATQ,

    A = k Γ— b (Where β€˜k’ is proportionality constant)

    ATQ;

    30 = k Γ— (1.2 Γ— 30)

    Or, k = (5/6)

    So, required value = (5/6) Γ— 54 = 45
