In a certain code language, CABLE is coded as 65@7#, and

?% of 1200.22 + 319.82 = 3.99 × 295.64

?% of (140.31 ÷ 19.97 × 80.011) = 139.98

30.05% of 149.97 + ? X 8.88 = (39.95 + 12.01² - 13.032²)² 

41.97 × 5.12 ÷ 2.99 + 49.89 = ?× 1.99

(8000)^1/3  × 10.11 × 8.97 ÷ 18.32 = ? + 25.022

?% of 309.99 = 40.01% of 249.99 + 295.98% of 49.99

(? + 11.86) X 14.89 = 19.89% of 2399.89

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

(32.25 × 14.98) + 31.76% of 1499.89 = ? × 3.67
