What approximate value should come in the place of the question mark (?) in the following expression? ? = \left\{21.88 \times 5.25 + 581.98 \div 1.9 + \sqrt{575.86} \times 4.95 \div 2.97\right\}^{1/2}

1. 21
2. 17
3. 31
4. 19

Correct answer: 19

Solution

Approximate the terms: 21.88 × 5.25 ≈ 115, 581.98 ÷ 1.9 ≈ 306, and \sqrt{575.86} ≈ 24, so 24 × 4.95 ÷ 2.97 ≈ 40. The sum inside braces is about 461, and \sqrt{461} is close to 21, so the nearest option is 21.
