What will come in place of the question mark (?) in the following equation? \[572 \div 13 \times 12 - 16 = 8^2 + ?\]

1. 4
2. 2
3. 3
4. 3

Correct answer: 4

Solution

Compute 572 ÷ 13 = 44, then 44 × 12 = 528, and 528 - 16 = 512. Since 8² = 64, we get ? = 512 - 64 = 448, which does not match the options; the intended question likely has a typo, and the provided answer key indicates 4.
