TuitionGoWhere Practice Paper - Mathematics Primary 6 PSLE

Answer Key — Whole Numbers, Version 3 of 5 (Total: 50 marks)

Section A (1 mark each)

1. 40,000 (4 ten-thousands)

2. 6,205,040

3. 4,863,000

4. $>$

5. 12 and 24

Section B (2 marks each)

6. $36 \div 4 + 5 \times 6 - 7 = 9 + 30 - 7 =$ 32

7. Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48; Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60. HCF = 12

8. Multiples of 12: 12, 24, 36, ...; Multiples of 18: 18, 36, ... LCM = 36

9. Rule: double the previous term and add 1. Next terms: $31 \times 2 + 1 =$ 63 and $63 \times 2 + 1 =$ 127

10. $5{,}982 \approx 6{,}000$ ; $21 \approx 20$ ; Estimated product $= 6{,}000 \times 20 =$ 120,000

Section C (3 marks each)

11. $1{,}250 \div 48 = 26$ remainder 2. The remaining 2 pupils still need a bus. Minimum number of buses = 27 buses

12. Let the number be $n$ . $8n - 35 = 245 \Rightarrow 8n = 280 \Rightarrow n =$ 35

Check: $35 \times 8 - 35 = 280 - 35 = 245$ . ✓

13. Larger number $= (156 + 38) \div 2 = 194 \div 2 =$ 97; Smaller number $= (156 - 38) \div 2 = 118 \div 2 =$ 59

Check: $97 + 59 = 156$ ; $97 - 59 = 38$ . ✓

14. Pattern: each new figure adds 3 matchsticks. Number of sticks in Figure $n$ = $3n + 1$ .

(a) Figure 15: $3 \times 15 + 1 = 45 + 1 =$ 46 matchsticks

(b) $3n + 1 = 100 \Rightarrow 3n = 99 \Rightarrow n =$ Figure 33

15. Boxes: $8{,}640 \div 24 = 360$ boxes. Cartons: $360 \div 15 =$ 24 cartons

Section D (4 marks each)

16. Cost of fans: $18 \times 125 = 2{,}250$ . Money left: $2{,}450 - 2{,}250 =$ $200

17. Total seats: $45 \times 36 = 1{,}620$ . Empty seats: $1{,}620 - 1{,}204 =$ 416 seats

18. (a) $7{,}250 \div 25 =$ 290 marbles in each bag

(b) Marbles removed: $25 \times 6 = 150$ . Marbles left: $7{,}250 - 150 =$ 7,100 marbles

19. Let Ben have $B$ at first; Siti had $2B$ . After the change: $2B - 84 = B + 36 \Rightarrow B = 120$ . Siti at first $= 2 \times 120 =$ $240

Check: Siti: $240 - 84 = 156$ ; Ben: $120 + 36 = 156$ . ✓

20. Continue the rule (multiply by 3, subtract 2):

5th term: $82 \times 3 - 2 = 246 - 2 = 244$
6th term: $244 \times 3 - 2 = 732 - 2 =$ 730
