**Q 1 - What is the original price of an apple if you got a 20% discount and paid $0.96 for it?**

### Answer : D

### Explanation

**Step 1:**

Let original price = *x*

Discount = 20% of *x* = 0.20*x*

**Step 2:**

Price after discount = *x* – 0.20*x* = 0.80*x* = $0.96

Dividing both sides by 0.80

$\frac{0.80x}{0.80} = \frac{0.96}{0.80} =$ $1.20; *x* = $1.20

**Step 3:**

So, original price = $1.20

**Q 2 - If you get 15% discount and pay $510 for a telephone, what is its original price?**

### Answer : B

### Explanation

**Step 1:**

Let original price = *x*

Discount = 15% of *x* = 0.15*x*

**Step 2:**

Price after discount = *x* – 0.15*x* = 0.85*x* = $510

Dividing both sides by 0.85

$\frac{0.85x}{0.85} = \frac{510}{0.85} =$ $600; *x* = $600

**Step 3:**

So, original price = $600

**Q 3 - If Peter pays $104 to buy a watch after a discount of 20%, find the original price of the watch.**

### Answer : C

### Explanation

**Step 1:**

Let original price = *x*

Discount = 20% of *x* = 0.20*x*

**Step 2:**

Price after discount = *x* – 0.20*x* = 0.80*x* = $104

Dividing both sides by 0.80

$\frac{0.80x}{0.80} = \frac{104}{0.80} =$ $130; *x* = $130

**Step 3:**

So, original price = $130

**Q 4 - What is the original price of a TV set if you paid $1170 for it after a discount of 10%?**

### Answer : A

### Explanation

**Step 1:**

Let original price = *x*

Discount = 10% of *x* = 0.10*x*

**Step 2:**

Price after discount = *x* – 0.10*x* = 0.90*x* = $1170

Dividing both sides by 0.90

$\frac{0.90x}{0.90} = \frac{1170}{0.90} =$ $1300; *x* = $1300

**Step 3:**

So, original price = $1300

**Q 5 - Mike bought a car for $18,900 after a discount of 30%. What was the original price of the car Mike bought?**

### Answer : C

### Explanation

**Step 1:**

Let original price = *x*

Discount = 30% of *x* = 0.30*x*

**Step 2:**

Price after discount = *x* – 0.30*x* = 0.70*x* = $18900

Dividing both sides by 0.70

$\frac{0.70x}{0.70} = \frac{18900}{0.70} =$ $27000;

**Step 3:**

So, original price = *x* = $27000

**Q 6 - If you buy 3 shirts, you get 10% discount. If you paid $189 for 6 shirts what is the original price of a T-shirt?**

### Answer : B

### Explanation

**Step 1:**

Let original price for 6 shirts = *x*

Discount = 10% of *x* = 0.10*x*

**Step 2:**

Price after discount = *x* – 0.10*x* = 0.90*x* = $189

Dividing both sides by 0.90

$\frac{0.90x}{0.90} = \frac{189}{0.90} =$ $210;

*x* = $210

**Step 3:**

Price of a single shirt = $\frac{210}{6}$ = $35

**Q 7 - If a Play Station was bought for $540 after a 10% discount, what was the original price of the Play Station?**

**Step 1:**

Let original price = *x*

Discount = 10% of *x* = 0.10*x*

**Step 2:**

Price after discount = *x* – 0.10*x* = 0.90*x* = $540

Dividing both sides by 0.90

$\frac{0.90x}{0.90} = \frac{540}{0.90} =$ $600;

**Step 3:**

So, original price = *x* = $600

Discount = 20% of *x* = 0.20*x*

**Step 2:**

Price after discount = *x* – 0.20*x* = 0.80*x* = $1920

Dividing both sides by 0.80

$\frac{0.80x}{0.80} = \frac{1920}{0.80} =$ $2400;

**Step 3:**

So, original price = *x* = $2400
