    • 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
