Find the approximate value of Question mark(?). No need to find the exact value.

59.88% of 419.78 + (24.09 × 5) ÷ 3 – √(80.81) = ?

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

157.78% of 4820 + 92.33% of 2840 = ? + 115.55% of 1980

(804/65) ÷ (11/798) × (129/131) = ?

(23.99)² – (17.99)² + (1378.88 + 44.88) ÷ ? = 607.998

25.04 × 22.03 + 383.92 ÷ ? + 23.78% of 1499.98 = 926.08 

20.11% of 119.99 + √80.97 ÷ 3.02 = ?

15.98% of 2199.9 = √? + 17.02% of 1799.97

(14.66)² + (343.84 ÷ 3.88 - 55.87) = ? + 91.23
