What approximate value should come in place of the question mark (?) in the following expression? You are not expected to calculate the exact value. $780.059 + 49.937 \times 30.079 - 59.591 = ?$

1. 2660
2. 5000
3. 2220
4. 2550

Correct answer: 2220

Solution

Approximate $49.937\approx 50$, $30.079\approx 30$, $780.059\approx 780$, and $59.591\approx 60$. Then the expression becomes about $780+50\times 30-60=780+1500-60=2220$.
