### Finding Cost Price when Selling Price and Profit or Loss are Given Examples

**Question 1.**

A charger was sold for $856 thereby gaining 12%. Find the cost price of the charger?

**Solution:**

Given that a charger was sold for $856 thereby gaining 12%.

The selling price = $856

Gain Percentage = 12%

We know that cost price = selling price × 100/100 + gain%

Substitute the selling price and the gain% in the above formula.

Cost price = $856 × 100/(100 + 12)

Cost price = $856 × 100/112

The Cost price = $85600/112 = $764.28

Therefore, the cost price of the charger is $764.28

**Question 2.**

By selling a motorcycle for $148, a shopkeeper loses 20%. How much percent would he gain or lose by selling it for $198?

**Solution:**

Given that by selling a motorcycle for $148, a shopkeeper loses 20%.

The selling price = $148

Loss Percentage = 20%

We know that cost price = selling price × 100/100 – loss%

Substitute the selling price and the loss% in the above formula.

Cost price = $148 × 100/100-20

Cost price = $148 × 100/80

The Cost price = $14800/80

Cost price = $185

Therefore, cost price of the bicycle = $185

Now, if the selling price = $198, then gain = $198 – $185 = $13

Therefore, gain% = gain/cost price × 100

= 13/185 × 100

= 7.027%

Therefore, he would have gained 7.027%.

**Question 3.**

An electronic device was sold for $1250 thereby gaining 10%. Find the cost price of the electronic device.

**Solution:**

Given that an electronic device was sold for $1250 thereby gaining 10%.

The selling price = $1250

Gain Percentage = 10%

We know that cost price = selling price × 100/100 + gain%

Substitute the selling price and the gain% in the above formula.

Cost price = $1250 × 100/(100 + 10)

Cost price = $1250 × 100/110

The Cost price = $1136.3636

Therefore, the cost price of the electronic device is $1136.3636

**Question 4.**

If the selling price of a book is $18 and the loss percent is 4%, then what is the cost price?

**Solution:**

Given that the selling price of a book is $18 and the loss percent is 4%.

The selling price of a book = $18

The loss percent is 4%.

Cost price = selling price × 100/100 – loss%

Substitute the selling price and the loss% in the above formula.

Cost price = $18 × 100/100 – 4

Cost price = $18 × 100/96

The Cost price = $1800/96 = $18.75

Therefore, the cost price of the book is $18.75

**Question 5.**

By selling an electrical mouse for $620, a trader gains 8%. Find the cost price of the mobile?

**Solution:**

Given that by selling an electrical mouse for $620, a trader gains 8%.

The selling price = $620

Gain Percentage = 8%

We know that cost price = selling price × 100/100 + gain%

Substitute the selling price and the gain% in the above formula.

Cost price = $620 × 100/(100 + 8)

Cost price = $620 × 100/108

The Cost price = $574.074

Therefore, the cost price of an electrical mouse is $574.074

**Question 6.**

Find out the cost price of the toy if the selling price is $1675 and the Loss is $77.

**Solution:**

Given that the selling price is $1675 and the Loss is $77.

The selling price of the toy = $1675

The loss = $77

Loss = Cost Price – Selling Price

Cost Price = Loss + Selling Price

Substitute the selling price and the loss in the above formula.

Cost Price = $77 + $1675

Cost Price = $1752

Therefore, the cost price of the toy is $1752.
