Solution:

1). (?)2 ≈ 420 / 35 × 300 / 25 = 12 × 300 / 25 = 12 × 12
? = √(12 × 12) = 12

2). (?)  ≈ √(196) × 7 + 627 = 14 × 7 + 627 = 98 + 627 = 725

3). ? = 19.99 × 15.98 + 224.98 + 125
≈ 20 × 16 + 225 + 125 = 320 + 225 + 125 = 670

4). ? ≈ 3215 +285 +600 – 4 = 4100 – 4 ≈ 4100

5). [(? × 1240) / 100] + [(60% of 450) / 100] ≈ 580
or, ? × 12.40 + 270 = 580
or. ? × 12.40 = 580 – 270 = 310
? = 310 / 12.40 = 25

6). 105.27% of 1200.11 + 11.80% of 2360.85 = 21.99% of ? + 1420.99
or, [(105 × 1200) / 100] + [(12 × 2360) / 100] = [(22 × ?) / 100] + 1421
or, [(22 × ?) / 100] = 1260 + 283.20 – 1421 ≈ 1543 – 1421 = 122
? = [(122 × 100) / 22] = [(122 × 50) / 11] = 11 × 50 = 550

7). 0.98% of 7824 + 4842 / 119.46 - ? = 78
or, 1% of 7824 + 4842 / 120 – 78 = ?
or, ? = [(1 × 7824) / 100] + (4842 / 120) – 78
≈ 78 + 40 – 78 = 40

8). [(41.99)2 – (18.04)2] / ? = (13.11)2 – 138.99
or, [(42)2 – (18)2] / ? = (13)2 – 139
or, [(42 + 18) (42 - 18)] / ? = 169 - 139
or, 60 × 24 / ? = 30
or, ? = 60 × 24 / 30 = 48

9). ? = (24.96)2 / (34.11 / 20.05) + 67.96 – 89.11
≈ (25)2 / (34 / 20) + 67.96 – 89
≈ 625 / 1.7 + 68 – 89
≈ 367 + 68 – 89 ≈ 346

10). √(2025.11) × √(256.04) + √(399.95) × √? = 33.98 × 40
or, √(2025) × √(256) + √(400) × √? = 1360
or, 20 × √? = 1360 – 720 = 640
or,  √? = (640 / 20) = 32
? = 32 × 32 = 1024
