SA2 Practice Paper — Topic Focus: Whole Numbers (Version 3 of 5) — Answer Key and Worked Solutions

Total Marks: 70

Section A (Questions 1–5, 2 marks each)

Q1: (a) 300,000 (b) 0 Q2: (a) 4,629,000 (b) 4,600,000 Q3: 845,032, 845,203, 845,230, 854,320 Q4: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 Q5: 61 — 24 + 8 × 5 − 12 ÷ 4 = 24 + 40 − 3 = 61

Section B (Questions 6–10, 3 marks each)

Q6: (a) 6,402,091 (b) 9,000,000 + 50,000 + 80 Q7: (a) 80 × 130 = 10,400 (b) 84 × 126 = 10,584 seats (c) 10,584 − 10,400 = 184 Q8: 42 — 84 = 2 × 2 × 3 × 7 and 126 = 2 × 3 × 3 × 7; HCF = 2 × 3 × 7 = 42 Q9: (a) 36 minutes (LCM of 12 and 18 is 36) (b) 08:36 (c) 4 times (08:00, 08:12, 08:24, 08:36) Q10: (90 − 24) ÷ 6 × 2 = 66 ÷ 6 × 2 = 11 × 2 = 22 ✓

Section C (Questions 11–15, 4 marks each)

Q11: (a) Each term = previous term × 2 + 1 (b) 63 × 2 + 1 = 127 (c) The 7th term. Continuing the pattern: 63 → 127 → 255. Alternatively, each term is one less than a power of 2 (3 = 2² − 1, 7 = 2³ − 1, …, 255 = 2⁸ − 1), so 255 is the 7th term. Q12: 123 — LCM of 8, 12 and 15 = 120; smallest number with remainder 3 = 120 + 3 = 123. Check: 123 ÷ 8 = 15 remainder 3; 123 ÷ 12 = 10 remainder 3; 123 ÷ 15 = 8 remainder 3. Q13: 34 × 47 + 15 = 1,598 + 15 = 1,613 Q14: (a) 5,394 + 2,468 = 7,862 (b) 5,394 + 7,862 = 13,256 Q15: 540 — LCM of 12, 18 and 30 = 180. The only multiple of 180 between 500 and 600 is 540. Check: 540 ÷ 12 = 45; 540 ÷ 18 = 30; 540 ÷ 30 = 18.

Section D (Questions 16–20, 5 marks each)

Q16: February = 12,450 − 1,275 = 11,175. Total = 12,450 + 11,175 = 23,625 toys Q17: Adults + children = 4 equal units. 1 unit = 1,856 ÷ 4 = 464 children (adults = 1,392) Q18: Number of bags = 864 ÷ 24 = 36. Money received = 36 × $9 = **$ 324** Q19: At first = 340 − 78 + 125 = 387 marbles Q20: (a) Tuesday = 145 × 3 = 435; Wednesday = 435 − 68 = 367 pens (b) Total = 145 + 435 + 367 = 947 pens
