**Q 1 - Trader A sells an item for $360 at 40% off; Trader B sells the same item for $300 at 30% off. Which is a better buy?**

### Answer : C

### Explanation

**Step 1:**

Discount of trader A = 40% of $360 = 0.4 × 360 = $144

Sale price of trader A = $360 − $144 = $216

**Step 2:**

Discount of trader B = 30% of $300 = 0.3 × 300 = $90

Sale price of trader B = $300 − $90 = $210

**Step 3:**

Since 210 < 216, purchasing from Trader B is a better buy.

**Q 2 - Trader A sells an item for $510 at 25% off; Trader B sells the same item for $540 at 30% off. Which is a better buy?**

### Answer : A

### Explanation

**Step 1:**

Discount of trader A = 25% of $510 = 0.25 × 510 = $127.50

Sale price of trader A = $510 − $127.50 = $382.50

**Step 2:**

Discount of trader B = 30% of $540 = 0.3 × 540 = $162

Sale price of trader B = $540 − $162 = $378

**Step 3:**

Since 378 < 382.50, purchasing from Trader B is a better buy.

Discount of trader A = 25% of $420 = 0.25 × 420 = $105

Sale price of trader A = $420 − $105 = $315

**Step 2:**

Discount of trader B = 30% of $460 = 0.3 × 460 = $138
