Solution(1):
(a) 16
[∵4 × 4 = 16]
(b) 24
[∵6 × 4 = 24]
(c) 8
[∵(4 × 4) – (2 × 4)
= 16 – 8
= 8]
(d) 12
[∵(6 × 4) – (3 × 4)
= 24 – 12
= 12]
(e) monkeys.
(f) lions.
2. Study the following graph carefully and fill in each blank.
Cartons of milk sold in a week | |
Monday | ☐☐☐ |
Tuesday | ☐☐☐☐☐ |
Wednesday | ☐☐☐☐☐☐☐☐ |

(d) ____ more cartons of milk were sold on Thursday than on Friday.
(e) ____ fewer cartons of milk were sold on Monday than on Friday.
(f) ____ cartons of milk were sold on Tuesday and Thursday.
Solution(2):
(a) Wednesday
(b) 10
[∵50 ÷ 5 = 10]
(c) 40
[∵4 × 10 = 40]
(d) 30
[∵(7 × 10) - (4 × 10)
= 70 – 40
= 30]
(e) 10
[∵(4 × 10) - (3 × 10)
= 40 – 30
= 10]
(f) 120
[∵(5 × 10) + (7 × 10)
= 50 + 70
= 120]
