Let’s solve each problem one by one, carefully checking our math.

Problem 32: 528 × 49 = ?
We can break this down:
528 × 50 = 26,400
But we want 528 × 49, which is 1 less group of 528.
So:
26,400 – 528 = ?
26,400 – 500 = 25,900
25,900 – 28 = 25,872
✔ So, 528 × 49 =
25,872

Problem 33: 58 cases × 24 cans per case = ?
Break it down:
58 × 24 = (50 × 24) + (8 × 24)
50 × 24 = 1,200
8 × 24 = 192
Total = 1,200 + 192 =
1,392
✔ Answer:
A

Problem 34: 40 teachers × 2500 sheets each = ?
40 × 2500 = ?
Think: 4 × 25 = 100 → then add three zeros (because 40 has one zero, 2500 has two zeros → total 3 zeros)
So: 100,000
✔ Answer:
B

Problem 35: 365 days × 24 hours/day = ?
We know:
365 × 24
Break it:
365 × 20 = 7,300
365 × 4 = 1,460
Add them: 7,300 + 1,460 =
8,760
✔ Answer:
D

Problem 36: 41 trucks × 1025 seats each = ?
Break it:
41 × 1000 = 41,000
41 × 25 = ?
40 × 25 = 1,000
1 × 25 = 25
→ 1,025
So total: 41,000 + 1,025 =
42,025
Wait — let me double-check:
Actually, 41 × 1025:
Better way:
(40 + 1) × 1025 = 40×1025 + 1×1025
40 × 1025 = 40 × (1000 + 25) = 40,000 + 1,000 = 41,000
Plus 1025 → 41,000 + 1,025 =
42,025

Problem 37: Morning trays: 62, Afternoon: 53 → Total trays = 62 + 53 = 115
Each tray holds 12 cookies → 115 × 12
Break it:
100 × 12 = 1,200
15 × 12 = 180
Total = 1,200 + 180 =
1,380
✔ Answer:
D

Problem 38: 9 rows, total 162 seats → seats per row = 162 ÷ 9
Do division:
9 × 18 = 162 → because 9 × 10 = 90, 9 × 8 = 72 → 90 + 72 = 162
