What approximate value should replace the question mark (?) in the following equation? ? \(\div (24.99 \times 12.01) + 19.9 - 119.99 \div 30.01 = 20\)

1. 1200
2. 1000
3. 100
4. 120

Correct answer: 1200

Solution

Approximating gives \(? \div (25\times 12) + 20 - 120\div 30 = 20\). So \(? \div 300 + 20 - 4 = 20\), which becomes \(? \div 300 = 4\). Hence \(? = 1200\).
