What approximate value should come in place of the question mark (?) in the following equation? 12.98 + 417.98 = 34.98 × 19.98 - ?² - 99.99

1. 11
2. 6
3. 21
4. 13

Correct answer: 6

Solution

Using approximation, 12.98 + 417.98 ≈ 430 and 34.98 × 19.98 ≈ 35 × 20 = 700. Then 430 ≈ 700 - ?² - 100, so ?² ≈ 170, and the closest option is 6.
