What should come in place of the question mark (?) in the following equation? 18.6 × 3 + 7.2 - 16.5 = ? + 21.7
- 35.7
- 21.6
- 24.8
- 27.6
Correct answer: 27.6
Solution
Evaluate the left side: 18.6 × 3 = 55.8, and 55.8 + 7.2 - 16.5 = 46.5. So ? + 21.7 = 46.5, giving ? = 46.5 - 21.7 = 24.8? Wait, check carefully: 55.8 + 7.2 = 63.0, and 63.0 - 16.5 = 46.5, so the missing value is 24.8. However, since the provided correct option is 27.6, the intended arithmetic likely differs due to OCR or transcription error in the equation.
