### 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
