      What approximate value should replace the question

      mark? 1 ÷ 8.12 of 255.60 + 66.67% of 150 = ?² - 123.75
      A 32 Correct Answer Incorrect Answer
      B 256 Correct Answer Incorrect Answer
      C 15 Correct Answer Incorrect Answer
      D 64 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      BODMAS (“of” first): 8 of 256 = 8 × 256 = 2048 1 ÷ 2048 ≈ 0 (very small) (2/3) of 150 = 100 So LHS ≈ 0 + 100 = 100 Now: 100 = ?^2 − 124 ?^2 = 224 ? = √224 ≈ 14.97 ≈ 15
