Percentage (P6) Practice
Master GST (9%), discount, profit, loss, and percentage change problems. Includes multi-step word problems where students must identify the correct base value β the most common error source in PSLE.
Common Mistakes to Avoid
Dividing by the new price instead of the original price in percentage change
Applying percentage increase/decrease in the wrong order
Forgetting that GST is applied to the price AFTER discount, not before
Practice Questions
Try each question. When you're stuck, reveal the Socratic strategy β a guided hint that teaches you how to think, not just what to write.
A bag originally costs $80. It is sold at a 15% discount. Find the selling price.
The price of a toy increased from $20 to $25. What is the percentage increase?
A laptop costs $1 200 before 9% GST. What is the final price?
Parent & Tutor Insight
Real-world shopping scenarios are the best preparation. Ask your child: 'If this $80 item has 30% off AND then 9% GST, what's the final price?' Working backwards from a receipt is even better.
