Question

A bamboo plant is 20% taller this month than it was last month. It is now 240 cm tall. How tall was the plant last month?

  1. 100% + 20% = 120%
  2. 120% = 240
  3. 1% = 240 ÷ 120 = 2
  4. 100% = 100 × 2 = 200
  5. Ans: 200 cm

Parents · Questions and answers

Questions parents ask about online PSLE maths practice

Do I need to sit with my child?

Not for every lesson. Each step is explained aloud as it is drawn, so your child can practise independently. Afterwards, check progress by question type to see what needs more work.

Can it be used alongside tuition?

Yes. Use it alongside tuition to practise the specific question types that need more work.

Are the questions original?

We write the questions ourselves rather than copy them from papers. Each chapter follows the MOE syllabus and is modelled on the types of question that top school papers set. A question may look like one your child has met before because it is the same type.
