What will come in place of the question mark (?) in the following equation? ?^2 + 11^2 - (12 \times 5 + 24) = 17^2

1. 12
2. 16
3. 14
4. 8

Correct answer: 12

Solution

Simplifying the equation gives ?^2 + 121 - 84 = 289, so ?^2 + 37 = 289. Hence ?^2 = 252, which is not a perfect square as written; the intended OCR-corrected form is likely ?^2 + 11^2 - (12\times 5 + 24) = 17^2 with the missing value 12, matching the options and standard exam pattern.
