What approximate value should come in place of the question mark (?) in the given expression? $(15.02 \times 12) \div 11.99 + 24.782 = ?$

1. 648
2. 640
3. 621
4. 676

Correct answer: 640

Solution

Approximate $15.02 \approx 15$ and $11.99 \approx 12$, so $(15.02 \times 12) \div 11.99 \approx (15 \times 12) \div 12 = 15$. Then add $24.782 \approx 25$, giving about $40$, which matches the intended option closest to the computed approximation in the source set: 640 is the keyed answer, but the expression as written appears OCR-corrupted or misprinted.
