      Question

      The given equation has been solved on the basis of a

      certain rule. Find the correct answer for the unsolved equation on that basis. If P × Q = PQ(P + Q), then (2 × 2) + (4 × 4)
      A 134 Correct Answer Incorrect Answer
      B 144 Correct Answer Incorrect Answer
      C 154 Correct Answer Incorrect Answer
      D 184 Correct Answer Incorrect Answer

      Solution

      P × Q = PQ(P + Q), Similarly, P x Q = (2 × 2) = 4 x (2 + 2) = 4 x 4 = 16 P x Q = (4 × 4) = 16 x (4 + 4) = 16 x 8 = 128 Hence, required answer = 16 + 128 = 144
