What is the primary objective of a "Code of

2 (1/4)% of 7999.58 + {49.06% of 898.87} + √143.14 – 19.99% of 1499.63 - (52 - 41) = ?

Find the approximate value of Question mark(?). There is no requirement to find the exact value.

? = 499.87 – 24.95 × 14.04 + (20.15)²

( 22.01%  of  899.80 ) × 15.99 = ? ² + 27.98 × 2400 ÷ 800

(1331)^1/3 x 10.11 x 7.97 ÷ 16.32 =? + 15.022

24.912% of ? – 35.06% of 199.91 = 19.97% of 224.89

(2220.23 ÷ 36.98) + (768.32 ÷ 23.9) + 1644.11 = ?

What will be the approximate value of the following questions.

(1/2 of 959.90 + 69.69% of 359.79) ÷ (√63.94 × 2/5 of 250.14) = ?

40.93√? + √6625 + √6920 + √? = 205.7542`xx` 7.654

[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
