Hardest PSLE Maths Questions Solved: Expert Tips & Practice

Understanding the Hardest PSLE Maths Questions

The PSLE (Primary School Leaving Examination) in Singapore is known for its challenging Maths paper, especially the problem-solving components that test higher-order thinking skills. In this blog post, we’ll explore some of the hardest PSLE Maths questions, provide detailed solutions, and offer tips to help you tackle similar problems effectively.

What Makes PSLE Maths Questions Difficult?

PSLE Maths questions are designed to test more than just basic arithmetic. These questions often include:

• Multi-step problems: Requiring students to solve several parts before arriving at the final answer.
• Conceptual understanding: Testing knowledge of mathematical principles rather than rote memorisation.
• Unfamiliar contexts: Presenting questions in scenarios students may not have encountered before.

Real-life Example: The Infamous Triangle Question

One of the most talked-about PSLE Maths questions in recent years was the 2019 ‘triangle question.’ Let’s break it down:

Question: In a triangle, the angle at vertex A is twice the angle at vertex B. The sum of the angles at vertex A and B is equal to the angle at vertex C. Find the measure of each angle.

Solution:

Here’s how to solve step-by-step:

1. Let the angle at vertex B be x.
2. The angle at vertex A is twice that of B, so it’s 2x.
3. The sum of angles A and B equals C, so 2x + x = C.
4. In a triangle, the sum of all angles is 180°. Hence, 2x + x + C = 180°.
5. Replace C with 3x: 2x + x + 3x = 180°.
6. Simplify: 6x = 180°.
7. Divide by 6: x = 30°.
8. Final angles: B = 30°, A = 60°, C = 90°.

Comparison: Hardest PSLE Maths Questions vs GCSE Maths

UK students preparing for GCSE Maths might find similarities in higher-order problem-solving questions. Here’s a comparison:

Aspect	PSLE Maths	GCSE Maths
Question Style	Often word problems requiring reasoning.	Includes word problems, algebraic proofs, and geometry questions.
Challenge Level	Designed to test critical thinking at primary school level.	Advanced, preparing students for A-Level and beyond.
Time Pressure	Limited time, especially for challenging sections.	Strict time limits for both calculator and non-calculator papers.

Exam Tips for Tackling Difficult Maths Questions

Whether you’re preparing for the PSLE or GCSE Maths, the following tips can help:

• Understand the question: Take time to read the problem carefully and identify what’s being asked.
• Break it down: Divide the problem into smaller, manageable steps.
• Use diagrams: Sketching can help clarify geometry and visualise solutions.
• Check your calculations: Always double-check to avoid careless errors.
• Practise similar questions: Familiarity is key. Explore a range of past paper questions.

Practice Questions

Test yourself with these challenging problems:

1. A rectangle has a length that is 3 times its width. The perimeter is 48 cm. Find the dimensions of the rectangle.
2. A shop sells apples at £0.50 each and oranges at £0.80 each. If a customer spends £5 buying 10 fruits, how many apples and oranges did they buy?
3. In a triangle, one angle is 45°, and another is twice the smallest angle. Find the measure of the third angle.
