Question
Find the approximate value of Question mark(?). There is
no requirement to find the exact value. ? = 200.14 + 27.98 × 16.05 − (10.03)² - 12.98% of 299.89Solution
200.14 + 27.98 × 16.05 − (10.03)² - 12.98% of 299.89 = 200 + 28 × 16 − (10)² - 13% of 300 28 × 16 = 448 (10)² = 100 13% of 300 = 39 200 + 448 − 100 – 39 = 509 Correct Answer: c
