Solve the given equation for ?. Find the approximate value.

[(49.88% of 320.11) × (34.85% of 460.24)] ÷ √783.94 = ?

(24.78 × 11.67) + (7199.67 ÷ 14.99) = ? × 12.65 

17.06 ² + √36.08 – (4.04/2.99) × 3.02 × 4.92 = ? × 4.99

What approximate value will replace the question mark (?) in the following?

√? + √626 × 13.998 - 6.02 × 2.97 = 345.995 

19.89% of 449.67 + 14.67% of 299.89 - 9.89% of 99.79 = ?

What will come in the place of question mark (?) in the given expression?

?² = {40% of (55² – 35² )} – 44
