  1. A shop sells apples in bags of 6 and oranges in bags of 4. What is the smallest number of each you must buy to have equal numbers of apples and oranges?

    Answer: 12 of each

    LCM of 6 and 4 = 12. You need 2 bags of apples (12) and 3 bags of oranges (12) to have 12 of each.

  2. A bus arrives every 12 minutes. The first bus arrives at 07:05. What time does the fourth bus arrive?

    Answer: 07:41

    First bus: 07:05. Second: 07:17. Third: 07:29. Fourth: 07:41. Each bus is 12 minutes after the previous one. Alternatively: 3 intervals × 12 = 36 minutes after 07:05 = 07:41.

  3. A square field has a perimeter of 200 metres. What is its area in square metres?

    Answer: 2,500 m²

    Side = 200 ÷ 4 = 50 m. Area = 50 × 50 = 2,500 m².

  4. Tom saves £5 in week 1, £10 in week 2, £15 in week 3, and so on. How much has he saved in total after 8 weeks?

    Answer: £180

    He saves £5n in week n. Total = 5(1+2+3+4+5+6+7+8) = 5 × 36 = £180.

  5. A drink is made by mixing juice and water in the ratio 1:4. How much water is needed to make 2 litres of drink?

    Answer: 1.6 litres

    Total parts = 1 + 4 = 5. Water = 4/5 × 2 = 1.6 litres.

  6. The temperature at 6 AM was -4°C. By noon it was 9°C. By how many degrees did the temperature rise?

    Answer: 13°C

    Rise = 9 - (-4) = 9 + 4 = 13°C.
