    Question

    Let’s assume, ‘p’ is directly proportional to

    ‘q’. Given that when p = 88, q = 44, calculate the value of ‘p’ when ‘q’ becomes 66.
    A 132 Correct Answer Incorrect Answer
    B 240 Correct Answer Incorrect Answer
    C 180 Correct Answer Incorrect Answer
    D 272 Correct Answer Incorrect Answer

    Solution

    ATQ,

    p ∝ q

    So, Let, p = k × q (where, ‘k’ is a proportionality constant)

    ATQ,

    88 = k × 44

    So, k = (88 / 44) = 2

    So, when ‘q’ = 66, then,

    p = 2 × 66 = 132
