Right Column (Problems 21–40):

These are missing number problems. We need to find the missing part.

21) $100 + \_\_\_ + 7 = 137$
→ $100 + x + 7 = 137$ → $x = 137 - 100 - 7 = 30$
✔ Answer: 30

22) $300 + 40 + \_\_\_ = 345$
→ $x = 345 - 300 - 40 = 5$
✔ Answer: 5

23) $\_\_\_ + 20 + 1 = 421$
→ $x = 421 - 20 - 1 = 400$
✔ Answer: 400

24) $\_\_\_ + 60 + 8 = 168$
→ $x = 168 - 60 - 8 = 100$
✔ Answer: 100

25) $500 + 75 = 575$
✔ Answer: 575

26) $400 + 23 = 423$
✔ Answer: 423

27) $100 + \_\_\_ = 147$
→ $x = 147 - 100 = 47$
✔ Answer: 47

28) $300 + \_\_\_ = 341$
→ $x = 341 - 300 = 41$
✔ Answer: 41

29) $72 + \_\_\_ = 872$
→ $x = 872 - 72 = 800$
✔ Answer: 800

30) $40 + 300 + \_\_\_ = 349$
→ $x = 349 - 40 - 300 = 9$
✔ Answer: 9

31) $8 + 70 + \_\_\_ = 678$
→ $x = 678 - 8 - 70 = 600$
✔ Answer: 600

32) $60 + 1 + 300 = 361$
✔ Answer: 361

33) $200 + 30 + 5 = 235$
✔ Answer: 235

34) $7 + \_\_\_ + 200 = 227$
→ $x = 227 - 7 - 200 = 20$
✔ Answer: 20

35) $400 + \_\_\_ + 50 = 456$
→ $x = 456 - 400 - 50 = 6$
✔ Answer: 6

36) $200 + 72 + 100 = 372$
✔ Answer: 372

37) $600 + 20 + 7 = 627$
✔ Answer: 627

38) $500 + \_\_\_ + 2 = 512$
→ $x = 512 - 500 - 2 = 10$
✔ Answer: 10

39) $6 + \_\_\_ + 600 = 636$
→ $x = 636 - 6 - 600 = 30$
✔ Answer: 30

40) $7 + 300 + \_\_\_ = 387$
→ $x = 387 - 7 - 300 = 80$
✔ Answer: 80

📝 Explanation:

- For addition problems (like 1–20), we simply add the hundreds, tens, and ones.
- For missing number problems (like 21–40), we subtract the known values from the total to find the missing number.
- Always remember to count hundreds first, then tens, then ones — this helps avoid confusion when adding or solving.
