What approximate value should come in the place of the question mark (?) in the following equation? $(4.28 \times 4.98)\%$ of $(29.89 \times 63.84) + 449.9 = 629.8 + ?$

1. 146
2. 192
3. 226
4. 176

Correct answer: 226

Solution

This is an approximation-based calculation. Rounding $4.28\approx4.3$, $4.98\approx5$, $29.89\approx30$, and $63.84\approx64$ gives a quick estimate close to the exact value. The resulting difference from 629.8 is approximately 226.
