Worked practice questions

A basket holds 20 apples and 5 oranges. What per cent of the fruits are oranges?

  1. 20 per cent
  2. 25 per cent
  3. 80 per cent
  4. 50 per cent
Show answer and solution

Correct answer: A. 20 per cent

1. Total fruits = 20 apples + 5 oranges = 25. 2. Fraction that is orange = 5/25. 3. Convert to per cent: (5/25) x 100 = 20. 4. So oranges are 20 per cent and apples the remaining 80 per cent. _Source: syllabus Maths Ch7 'Comparing Quantities', section 7.1_

Girls form 60 per cent of a class and there are 18 girls. How many students are in the class?

  1. 28
  2. 30
  3. 32
  4. 36
Show answer and solution

Correct answer: B. 30

1. Let the total number of students be x. 2. 60 per cent of x = 18, so (60/100) x = 18. 3. x = (18 x 100) / 60 = 30. 4. Check: 60 per cent of 30 = 18 girls, leaving 12 boys. _Source: syllabus Maths Ch7 'Comparing Quantities', Example 1_
