Find the simplified value of the given expression

?% of (√196) × 24 + 344 = 428
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
72% of 400 – 23% of 1020 = 120% of ?Â
What will come in the place of question mark (?) in the given expression?
48 X 2.5 + 20% of 150 = ? + 166
[564 + 32 of 18 × 9 ÷ 12 + 162 ] ÷ 4 = ?
What value should come in the place of (?) in the following questions?
3? = 81 ÷ 312 * 27 * 94
104 × 21 ÷ 13 + ? % of 300 = 320 + 22
