Find the approximate value of question mark (?) in the following questions.

1259.909 ÷ 12.106 ÷ 6.979 + 37.8982 – 29.9023 = ?

Find the approximate value of:
​$$\frac{76.91 × 143.97}{7.07 × 12.01} - \frac{3.93^2 × \sqrt{195.88}}{6.93 × 8.03^{\frac{1}{3}}}$$​​

​$$\frac{779.23}{13} + 4.98 + 23 = \frac{x}{100} \times 60.03$$​​

1259.909 ÷ 12.106 ÷ 6.979 + 37.8982 – 29.9023 = ?

6561.01 ÷ (8.98 × 3.01) ÷ 2.98 = ?

Which of the following options is the closest approximate value which will come in place of the question mark (?) in the following equation?
625 × 31 ÷ 233 – 59 = ?

Which of the following options is the closest approximate value which wilt come in place of the question mark (?) in the following equation?

​$$75.02 \div 16.89 × 13.47 + 749.98 – 79.29 = ?$$​
