What is Profit & Loss Formula?
The profit and Loss formula is used to determine the price of an item and understand how profitable a business is.
Every product has a cost price and selling price and based on the values of these prices, you can find out the profit gained or loss incurred on a particular product.
Scroll down to learn short tricks to solve profitloss questions in the aptitude exams.
Basic Concepts of Profit and Loss
Before diving into the realm of short tricks for calculating costs, profits, and discounts, let's familiarize ourselves with some basic concepts and formulas. Understanding these fundamental terms will provide a solid foundation for mastering the shortcuts later on.
1. Cost Price (CP):
The Cost Price refers to the price at which an item is purchased. This value can be further classified into two types:
a) Fixed Cost:
The Fixed Cost is a constant price that remains unchanged under any circ*mstances. It does not fluctuate based on the number of units.
b) Variable Cost:
On the other hand, the Variable Cost can vary depending on the number of units. As the quantity increases or decreases, the cost also changes accordingly.
2. Selling Price (SP):
The Selling Price represents the price at which an item is sold. It is the amount that a customer pays to acquire the product or service.
3. Profit or Gain (P):
Profit or Gain is the positive financial outcome achieved when the Selling Price exceeds the Cost Price. In simple terms, if you sell an item for more than what you paid for it, the difference between the Selling Price and the Cost Price is considered profit.
4. Loss (L):
Conversely, Loss occurs when the Selling Price is less than the Cost Price. In such cases, the difference between the Selling Price and the Cost Price represents the loss incurred.
5. Marked Price (MP):
The Marked Price, also known as the Listed Price, is the price set by shopkeepers or sellers as the original value of the product. It serves as a reference point from which discounts are offered to customers.
6. Discount:
A Discount refers to the reduction in price offered on the Marked Price. It is a deduction made from the original price to incentivize customers and encourage sales.
Having a clear understanding of these basic concepts and formulas related to cost, profit, loss, marked price, and discount is crucial for performing calculations effectively.By grasping these fundamental concepts, you will be better equipped to navigate the world of pricing and financial transactions.

Short Tricks to Solve Profit Loss Questions in CLAT Aptitude Exam 2025
To effectively solve profit and loss questions in the CLAT aptitude exam 2025, it is essential to employ some useful tricks. Here are some important math formulas that can help you solve profit and loss problems within 10-15 seconds:
Profit Calculation: Profit (P) = Selling Price (SP) - Cost Price (CP); SP > CP
Loss Calculation: Loss (L) = CP - SP; CP > SP
Profit Percentage: P% = (P/CP) x 100
Loss Percentage: L% = (L/CP) x 100
Selling Price Calculation: SP = [(100 + P%)/100] x CP
Selling Price Calculation (Alternative): SP = [(100 - L%)/100] x CP
Cost Price Calculation: CP = [100/(100 + P%)] x SP
Cost Price Calculation (Alternative): CP = [100/(100 - L%)] x SP
Discount Calculation: Discount = Marked Price (MP) - SP
Selling Price Calculation (Alternative): SP = MP - Discount
Equivalent Loss Percentage: If P% and L% are equal, then %loss = P2/100
Net Percentage Profit or Loss: When the profit is x% and the loss is y%, the net % profit or loss will be: (x - y - xy)/100
Calculation of Actual Cost Price: If a product is sold at x% profit and then again sold at y% profit, the actual cost price of the product will be: CP = [100 x 100 x P/(100 + x)(100 + y)]. In the case of loss, CP = [100 x 100 x P/(100 - x)(100 - y)]
Profit Percentage for False Weight: For false weight, profit percentage will be: P% = (True weight - false weight/ false weight) x 100
Net Percentage Profit with Two Successful Profits: When there are two successful profits, say x% and y%, the net percentage profit equals: (x + y + xy)/100
These profit and loss formulas and tricks can serve as valuable tools for your preparation. It is recommended to take note of these formulas or revisit this article for revision as needed.
Important Profit & LossQuestions
Solving previous years' question papers for the CLAT exam can provide valuable insights into the difficulty level and types of questions asked. Let's take a look at some important profit and loss questions and their solutions.
Question 1:
A dishonest merchant sells his grocery using weights that are 15% less than the true weights and manages to make a profit of 20%. What is his total gain percentage?
Solution:
Let's assume the weight of a grocery bag to be 1 kg. The actual weight, considering the 15% reduction, is 85% of 1000 grams, which equals 850 grams. If we consider the cost price of each gram to be Re. 1, then the cost price of each bag is Rs. 850.
The selling price of 1 kg of bag is 120% of the true cost price. Therefore, SP = 120/100 x 1000 = Rs. 1200.
The gain is calculated as the difference between the selling price and the cost price: Gain = 1200 - 850 = Rs. 350.
Hence, the gain percentage is calculated as (350/850) x 100 = 41.17%.

Question 2:
A shopkeeper allows a discount of 10% on the marked price and still manages to gain 17% on the whole. What percentage above the cost price did he mark his goods?
Solution:
Let's assume the cost price to be 100. The selling price is then 117 (since the shopkeeper gained 17%).
Let the marked price be represented as x. If a discount of 10% is applied to x, it becomes 90% of x. We have the equation: 90% of x = 117, which can be simplified to x = 130.
Therefore, the shopkeeper marked his goods 30% above the cost price.

Question 3:
A shopkeeper buys 1 kg of apples for Rs. 100 and sells them for Rs. 120 per kg. What is the profit gained by the shopkeeper?
Solution:
The cost price of the apples is Rs. 100, and the selling price is Rs. 120.
The profit gained by the shopkeeper can be calculated as follows: Profit = Selling Price - Cost Price = Rs. 120 - Rs. 100 = Rs. 20.
______________________________
Question 4:
If a pen costs Rs. 50 after a 10% discount, what is the pen's actual price or marked price?
Solution:
Let's assume the marked price to be MP. After a 10% discount, the pen costs Rs. 50.
Using the formula: MP x (100 - 10) / 100 = 50, we can solve for MP:
MP x (90/100) = 50
MP = (50 x 100) / 90
Therefore, the pen's actual price or marked price is Rs. 55.55.
______________________________
Question 5:
A man bought some toys at the rate of 10 for Rs. 40 and sold them at 8 for Rs. 35. What is his gain or loss percentage?
Solution:
The cost price of 10 toys is Rs. 40, so the cost price of 1 toy is Rs. 4.
The selling price of 8 toys is Rs. 35, which means the selling price of 1 toy is Rs. 35/8.
The gain is calculated as the difference between the selling price and the cost price of 1 toy: Gain = (35/8) - 4 = 3/8.
Hence, the gain percentage is calculated as [(3/8)/4] x 100 = 9.375%.
______________________________
Question 6:
A trader sells 85 meters of cloth for Rs. 8,925 with a profit of Rs. 15 per meter of cloth. What is the cost price of 1 meter of cloth?
Solution:
The selling price of 1 meter of cloth is calculated by dividing the total selling price by the total quantity: SP of 1 meter of cloth = Rs. 8,925 / 85 = Rs. 105.
The cost price of 1 meter of cloth is obtained by subtracting the profit on 1 meter of cloth from the selling price: CP of 1 meter of cloth = Rs. 105 - Rs. 15 = Rs. 90.
