We will learn how to calculate loss percent in an article. Loss percentage is always calculated on cost price (C.P.).
Formula to find loss% = (loss/cost price) × 100%
Solved examples:
1. By selling a machine for $9000; a loss of $1000 is suffered. Find the loss percent.
Solution:
Given, S.P. of a machine = $9000 and loss made = $1000
Therefore, C.P. = S.P. + loss
= $9000 + $1000
= $10000
And, loss% = (loss/cost price) × 100%
= (1000/10000) × 100%
= (1/10) × 100%
= 10%
Therefore, loss percent by selling a machine is 10%

2. By selling an article for $10000 a man losses $2000. Find the loss%.
Solution:
Given, selling price of an article = $10000 and loss made = $2000
Therefore, cost price = selling price + loss
= $10000 + $2000
= $12000
And, loss% = (loss/cost price) × 100%
= (2000/12000) × 100%
= (1/6) × 100%
= 16 2/3%
Therefore, loss percent by selling an article is 16 2/3%.
3. Jim bought a second hand motorcycle for $1200 and spent $200 on its repair. He sold it for $1280. Find his loss percent.
Solution:
Cost price includes overhead expenses also.
Therefore, cost price = $1200 + $200 = $1400
and selling price = $1280
Since, selling price < cost price, there is a loss.
Loss = cost price  selling price
= $1400  $1280
= $120
Loss percent = loss/cost price × 100
= 120/1400 × 100
= 60/7
= 8 4/7 %
Therefore, loss percent by selling a second hand motorcycle is 8 4/7 %
Note:
When some additional expenses are made after purchase of an article, it is added to the cost price (C.P.), these additional expenses are called overhead.
