What approximate value will come in place of question mark (?) in the following question. (You are not expected to calculate the exact value)

(24.98% of 880.2)/10.99 + 39.98% of 200 = √(?)

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

What approximate value will come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value)
(4.12²× 11.99) + ? = 45.22% of 5000

What approximate value will come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value)
3/7th of 83 + ? = 234.99 × 2.99

1259.909 ÷ 12.106 ÷ 6.979 + 37.8982 – 29.9023 = ?
