Answers:

  1. 5; ? = 415.25 – 627.10 + 958.55 = 1373.80 – 627.10 = 746.70
  2. 3; ? = 34928 – 2591 – 14986 = 34928 – 17577 = 17351
  3. 5; ? = 147/7 × 0.3 = 210/3 = 70
  4. 3; 311 × 17 – 2482 = 5287 – 2482 = 2805
  5. 3; 12.5 × 6.7 × 4.2 = 351.75
  6. 3; ? × 375/100 = 27 × 450/100 – 76.5
    • = 27 × 4.50 – 76.5 = 121.5 – 76.5 = 45
    • ∴ ? = 45 × 100/375 = 4500/375 = 12
  7. 4; ? = 5038 – (4567.8 + 14 × 9.8)
    • = 5038 – (4567.8 + 137.2) = 5038 – 4705.0
    • = 333
  8. 5; ? = 1632/51 = 32
  9. 1; ? = 53/3 × 123/106 = 41/2 = 201/2
  10. 5; ? = 6924/15 × 4 = 115.4
  11. 2; 8888 – 4444 + 222 = 9110 – 4444 = 4666
  12. 4; 1734.5 × 1768.9 ÷ 1727.4 = 17?
    • = 1734.5 + 68.9 – 27.4 = 171034 – 27.4 = 1776
    • ∴ ? = 76
  13. 4; ? = 23 × 468/100 = 23 × 4.68 = 107.64
  14. 1; ? = 63 × 24 – 92 = 216 × 16 – 81
    • = 3456 – 81 = 3375
  15. 2; ? ÷ 26 × 17 = 7225
    • or, ?/26 = 7225/17 = 425
    • ∴ ? = 425 × 26 = 11050
