What should come in place of the question mark in the following expression? $(63.99)^{1/3} \times 124.989 + 407.05 \div 10.98 = ?$

1. 537
2. 425
3. 754
4. 224

Correct answer: 537

Solution

The expression is meant for approximation. $(63.99)^{1/3} \approx 4$, $124.989 \approx 125$, and $407.05 \div 10.98 \approx 37$. So the value is approximately $4 \times 125 + 37 = 537$.
