What approximate value should come in place of the question mark (?) in the following expression? $(49.95 \times 12.12) - (19.98 \times 7.95) - (1.98 \times 60.05) = ?$

1. 350
2. 320
3. 400
4. 460

Correct answer: 320

Solution

Approximating the numbers gives $50\times12 - 20\times8 - 2\times60 = 600 - 160 - 120 = 320$. So the closest value is 320.
