  1. Which statement about all squares is true?

    Answer: All squares are rectangles

    A square has all the properties of a rectangle (four right angles, opposite sides equal), so all squares are rectangles.

  2. In a class, 18 students like soccer, 14 like basketball, and 8 like both. How many students like at least one sport?

    Answer: 24

    Using inclusion-exclusion: 18 + 14 − 8 = 24 students like at least one sport.

  3. A car park has 3 levels with 40 spaces on each level. On Monday morning, ¾ of spaces are taken. How many spaces are free?

    Answer: 30

    Total spaces = 120; ¾ × 120 = 90 taken; 120 − 90 = 30 free spaces.

  4. If today is Wednesday, what day will it be in 100 days?

    Answer: Friday

    100 ÷ 7 = 14 remainder 2, so add 2 days to Wednesday: Thursday, Friday.

  5. A fence is built around a square garden with a perimeter of 48 m. What is the area of the garden?

    Answer: 144 m²

    Each side = 48 ÷ 4 = 12 m; area = 12 × 12 = 144 m².

  6. Three friends share a pizza. Emma eats ½, Jack eats ⅓, and Lily eats the rest. What fraction does Lily eat?

    Answer: 1/6

    Emma + Jack = ½ + ⅓ = 5/6; Lily eats 1 − 5/6 = 1/6.
