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

Solve the following expression and calculate the approximate value.

( 19.95%  of  799.89 ) × 12.05  =  ? ² + 18.99 × 6250 ÷ 1250

? = 41.92% of (34.92 x 40.42) + 29.78% of 399.84

(23.95)² – (25.006)² + (8.0099)² – (7.07)² = ? - (14.990)²

15.23² + 39.98% of 539.99 = ? × 6.99

1080.04 – 250.18 + 199.98 ÷ 20.06 = ?

(√845 ×19.932+ √4230 ×14.385)/(√1765 ×4.877 ) = ?
