What approximate value should come in the place of the question mark (?) in the given equation? 31.9 × 55.011 - ? = (12.01)^3 + 7.94% of 250.14

1. 8
2. 33
3. 17
4. 12

Correct answer: 12

Solution

Using approximation, 31.9 × 55.011 is about 1755 and (12.01)^3 is about 1731. Also, 7.94% of 250.14 is about 20, making the right side about 1751. Hence the missing value is approximately 12.
