Sample Questions
1. A store marks up an item by 25% above its cost price, then offers a 20% discount on the marked price during a sale. If the item's cost price is ₱400, what is the final sale price?
- A. ₱400
- B. ₱420
- C. ₱500
- D. ₱480
Correct answer: A — ₱400
Marking up ₱400 by 25% gives a marked price of ₱500 (400 × 1.25). Applying a 20% discount to that marked price gives 500 × 0.8 = ₱400 — the increase and decrease happen to exactly cancel out here (1.25 × 0.8 = 1.0). A common mistake is subtracting the percentages directly (25% − 20% = 5%) and computing 400 × 1.05 = ₱420, which ignores that percentage changes compound multiplicatively, not additively.
