Profit And Loss formula
Commercial Mathematics of Class 8
The situations described in this topic are from the point of view of the person selling something to someone else.
The 'cost price' is how much the item cost the shop owner.
The 'selling price' is what he is selling it for.
If the shop sells a thing for more than they paid for it, then the difference is the 'profit':
Profit = selling price - cost price
If the shop sells a thing for less than they paid for it, then the difference is the 'loss':
Loss = cost price - selling price
Both profit and loss can be expressed either in Rupees, OR as a percentage of the cost price.
Question 1. A shopkeeper buys scientific calculators in bulk for Rs.150 each. He sells them for Rs. 175 each.Calculate the profit on each calculator in rupees, and as a percentage of the cost price.
Solution: cost price = Rs.150, selling price = Rs.175
profit = selling price - cost price
= Rs. 175 – Rs.150
= Rs. 25
Expressing the profit as a percentage of the cost price:
Profit % =
