  1. A number is multiplied by 6 and then 15 is subtracted to give 45. What is the number?

    Answer: 10

    6n − 15 = 45, so 6n = 60, giving n = 10.

  2. What is 15% of 200?

    Answer: 30

    15% of 200 = 0.15 × 200 = 30.

  3. A square has a perimeter of 36 cm. What is its area?

    Answer: 81 sq cm

    Side = 36 ÷ 4 = 9 cm, Area = 9² = 81 sq cm.

  4. What comes next in the pattern: 2, 5, 10, 17, ___?

    Answer: 26

    The differences between consecutive terms increase by 2 each time (3, 5, 7, 9...), so 17 + 9 = 26.

  5. If it takes 5 workers 8 days to complete a job, how many days would 10 workers take?

    Answer: 4

    10 workers is double, so they take half the time: 8 ÷ 2 = 4 days.

  6. What is 0.25 expressed as a fraction in simplest form?

    Answer: 1/4

    0.25 = 25/100 = 1/4 when simplified.
