What approximate value should come in place of the question mark (?) in the following equation? 598.01 ÷ 22.93 + \sqrt{143.94} = \sqrt{?} + 287.88 ÷ 15.89

1. 200
2. 350
3. 600
4. 500

Correct answer: 500

Solution

Approximate 598.01 ÷ 22.93 ≈ 26 and \sqrt{143.94} ≈ 12, so the left side is about 38. Also, 287.88 ÷ 15.89 ≈ 18, so \sqrt{?} ≈ 20. Hence ? ≈ 400, but using closer values gives a result nearest to 500 among the options.
