Explanation:

1. 27.5% of 250-121×4÷176×√529 = ?

       55% of 125-121×4÷176×23 = ?

       68.75-63.25 = ?

       ? = 5.5

2. 

    (3441.25-6423.75+3742.50)/(8+31-26) = ?/52

     760/13 = ?/52

     ? = 3040

3. √(1089) ×121×∛(64) ÷528÷∛(1331) +216-130.75 = ?

    33 ×121×4 ÷528÷11 +216-130.75 = ?

    2.75+216-130.75 = ?

    ? = 88

4. ?% of 630-70% of 1296 = 121.8

    ?% of 630 = 121.8+907.2

    ?% of 630 = 1029

    ? = 163.33

5. 

     (2+5-3+1-3) +3/4+4/8-5/12+3/4-1/12 = ?

     2+(18+12-10+18-2)/24 = ?

     2+3/2 = ?

     ? = 3.5

6. 13, 25, 49, ?, 193, 385

    13×2-1 = 25

    25×2-1 = 49

    49×2-1 = 97

    97×2-1 = 193

    193×2-1 = 385

7. 19, 23, 32, 48, ?, 109

    19+4 = 23

    23+9 = 32

    32+16 = 48

    48+25 = 73

    73+36 = 109

8. 16, 36, 69, 114, ?, 236

    16+(20) = 36

    36+(20+13) = 69

    69+(33+12) = 114

    114+(45+11) = 170

    170+(56+10) = 230

9. 8, 4, ?, 6, 12, 30

    8×.5 = 4

    4×1 = 4

    4×1.5 = 6

    6×2 = 12

    12×2.5 = 30

10. 10, 22, 39, 61, 88, ?

      10+12 = 22

      22+(12+5) = 39

      39+(17+5) = 61

      61+(22+5) = 88

      88+(27+5) = 120
