Question 1

A jacket costs $80. In a sale it is reduced by 25%. What is the sale price?

  • A.$20
  • B.$55
  • C.$60
  • D.$75
Answer & worked solution

Answer: C) $60
25% of $80 = $20. Sale price = $80 − $20 = $60.

Question 2

A total of $48 is shared in the ratio 3 : 5. How much is the larger share?

  • A.$18
  • B.$24
  • C.$30
  • D.$40
Answer & worked solution

Answer: C) $30
3 + 5 = 8 parts. $48 ÷ 8 = $6 per part. The larger share is 5 × $6 = $30.

Question 3

At dawn the temperature is −3 °C. By midday it has risen by 8 °C. What is the temperature at midday?

  • A.−11 °C
  • B.−5 °C
  • C.5 °C
  • D.11 °C
Answer & worked solution

Answer: C) 5 °C
Start at −3 and add 8: −3 + 8 = 5 °C.

Question 4

If 3x + 4 = 19, what is the value of x?

  • A.3
  • B.5
  • C.6
  • D.7
Answer & worked solution

Answer: B) 5
Subtract 4 from both sides: 3x = 15. Then divide by 3: x = 5.

Question 5

  • A.16 cm²
  • B.30 cm²
  • C.32 cm²
  • D.60 cm²
Answer & worked solution

Answer: B) 30 cm²
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 cm². (60 cm² forgets the ½.)

A bag holds 3 red and 5 blue marbles. One marble is drawn at random. What is the probability it is red?

  • A.1/3
  • B.3/8
  • C.3/5
