Introduction to Profit and Loss for CAT
To understand the topic, you must understand the basic definitions first, like
CP (Cost Price): It is the price at which an article is purchased.
SP (Selling Price): It is the price at which an article is sold.
MP (Marked Price or List Price): It is the price marked on the article. Discounts are generally calculated on this price.
Profit or Gain: When SP > CP, the seller makes a profit.
Profit = SP - CP
Loss: When CP > SP, the seller incurs a loss.
Loss = CP - SP
Discount: It's a reduction given on the marked price (MP).
Discount = MP – SP
Also, you should understand the question types that are being asked in the CAT
Questions based on CP, SP, and MP
When CP, discount%, Profit% are given, and other variables like SP, MP, etc need to be calculated.
Questions based on successive discounts

Common mistakes students make in Profit & Loss CAT questions
It is important to understand the common mistakes in the CAT exam that a student makes while solving the Profit and Loss questions.
Common Mistakes
How to Rectify
Ignoring basic concepts
Understand all the basic definitions and formulas, and practice questions based on them
Misinterpreting the base
Usually, students calculate the profit percent on the selling price instead of the cost price. So, it is very important to understand that the profit is always calculated on CP, discount is always calculated on MP.
Mistakes in converting percentages into fractions
Practice the percentage to fraction conversion and vice versa.
Errors in finding successive discounts
It is important to understand whether the successive discounts are needed or not. You should focus more and practice more
When questions involve two or more concepts, students often make mistakes
Practice questions based on the concept amalgam.
The Only 3 Profit and Loss Formulas You Need for CAT
There are 3 basic formulas in profit and loss that need to be understood to solve any question in Profit and loss. The rest are the variations of the questions.
Formula 1 (Relating SP, CP, and Profit/Loss)
Profit $\% = \frac{\text{Profit}}{\text{CP}} \times 100$, where CP is the cost price.
Loss $\% = \frac{\text{Loss}}{\text{CP}} \times 100$, where CP is the cost price.
Profit $= \text{SP} - \text{CP}$, Loss $= \text{CP} - \text{SP}$
Other Variations of this formula: $\text{SP} = \text{CP} \times \frac{100 + \text{Profit}\%}{100}$
Key Usage: Basic P&L questions, cost-price/selling-price direct problems.
Example: A shopkeeper buys a book for ₹400 and sells it at ₹460. Find profit %.
Key Usage: Marked price, hike in the price of value, successive increase in the price.
Example: A man marked up the price on one article by $20\%$ and lost $10\%$ on the marked price while selling. Find net % gain/loss.
Let $CP = 100$. After increase of $20\%$, price $= 120$. After second transaction, final $SP = 120 \times 0.9 = 108$.
Net gain% $= \dfrac{108 - 100}{100} \times 100 = 8\%$.
How to Solve Profit and Loss in CAT Using These Formulas
A few points must be remembered before solving questions using these 3 formulas
1. Profit or loss percent is always calculated on the cost price.
2. Discount percent is always calculated on the marked price.
3. The markup percent is always calculated on the cost price.
Also, there are some prerequisite conditions:
Hands-on percentage to fraction conversion and vice versa.
Step-by-step approach to Profit & Loss CAT questions
Consider the following example:
Question: A man buys 35 kg of sugar and sets a marked price in order to make a 20% profit. He sells 5 kg at this price, and 15 kg at a 10% discount. Accidentally, 3 kg of sugar is wasted. He sells the remaining sugar by raising the marked price by p percent so as to make an overall profit of 15%. Then p is nearest to: [CAT 2024]
Solution:
Step 1: First, understand the problem statement and the information given in the question.
In this question, the markup percent is to be calculated.
Given:
Targeted Profit % = 20%
Sold 5 kg at the targeted price.
Sold 15 Kg at a discount of 10%.
3 kg of sugar is wasted.
Now, we need to find the percentage increase in the price of the remaining sugar so that the total profit is 15%.
Step 2: Identify the concept required to solve the question.
Formula 1 should be used in between
Profit/Loss % = $\dfrac{Profit\ or\ Loss}{CP} \times 100\%$, where $CP$ is the cost price.
Formula 2 (used in between):
Discount % = $\dfrac{Discount}{MP} \times 100\%$, where $MP$ is the marked price.
Formula 3 (used in the end):
Markup % = $\dfrac{Markup\ Value}{CP} \times 100\%$, where $CP$ is the cost price.
Step 3: Apply the concept/formula to find the unknown.
Final Solution:
Let the cost price of 1kg of sugar = Rs 100
The total cost price of 35 kg = Rs 3500
Marked price per kg = Rs 120
Given, the final profit is 15%. So, Final SP of 35 kg = 3500 × 1.15 = Rs 4025
First 5 kg's are sold at 20% marked-up price, SP1 = 5 × 100 × 1.2 = Rs 600
Next 15 kg are sold after giving 10% discount, SP2 = 15 × 100 × 1.2 × 0.9 = Rs. 1620
3 kg of sugar got wasted
$\Rightarrow 23 \text{ kg of sugar was sold at } Rs.\ (600 + 1620) = Rs.\ 2220$
The remaining $12 \text{ kg}$ should be sold at $Rs.\ (4025 - 2220) = Rs.\ 1805$
$\Rightarrow SP \text{ of 1 kg } = \dfrac{1805}{12} \approx Rs.\ 150$
Hence, the seller should further mark up by
$\dfrac{150 - 120}{120} \times 100 = 25\%$
Identifying shortcut opportunities in CAT Quant
Here are a few shortcuts that can be helpful to solve the questions effectively and save time during the exam.
Concept
Shortcut
To find the net profit or loss percent if the cost price of n articles is the same.
Average of all profit and loss percentages. Profit percentages are taken as positive, while loss percentage is taken as negative.
To find the net profit or loss percent if the selling price of 2 articles is the same and the profit % (x%) and loss % (x%) are the same.
$\text{Net Loss %} = \dfrac{x^2}{100}$
Net discount if there are two successive discounts of $R_1\%$ and $R_2\%$.
Solved Past 5 Years’ Questions with Solutions of Profit and Loss for CAT
Q.1) Bina incurs 19% loss when she sells a product at Rs. 4860 to Shyam, who in turn sells this product to Hari. If Bina would have sold this product to Shyam at the purchase price of Hari, she would have obtained 17% profit. Then, the profit, in rupees, made by Shyam is
Solution:- [Expected time to be taken: 45 to 60 seconds, Level of Difficulty: Moderate]
Let the cost price for Bina be $x$.
Bina sells to Shyam at a 19% loss: $4860 = x - \frac{19}{100}x = \frac{81}{100}x$
So, $x = \frac{4860 \times 100}{81} = 6000$
Now, let the selling price to Hari be $y$.
If Bina had sold to Shyam at Hari's price and made 17% profit: $y = x + \frac{17}{100}x = \frac{117}{100} \times 6000 = 7020$
So, Shyam bought at Rs. 4860 and sold at Rs. 7020
Therefore, his profit is: $7020 - 4860 = 2160$
Hence, the correct answer is $2160$.
Q.2) Gopi marks a price on a product in order to make $20 %$ profit. Ravi gets $10 %$ discount on this marked price, and thus saves Rs 15. Then, the profit, in rupees, made by Gopi by selling the product to Ravi, is
A) 15
B) 25
C) 10
D) 10
Solution:- [Expected time to be taken: 45 seconds, Level of Difficulty: Easy]
Let the cost price of the product be $100x$.
Gopi wants to make a $20\%$ profit, so the marked price (MP) is:
But the question says Ravi saves Rs 15, So, $12x=15$
$⇒x=\frac{15}{12}=\frac54$
The profit made by Gopi = $108x - 100x = 8x= 10$ rupees.
Hence, the correct answer is option 3.
Q.3) Gita sells two objects A and B at the same price such that she makes a profit of 20% on object A and a loss of 10% on object B. If she increases the selling price such that objects A and B are still sold at an equal price and a profit of 10% is made on object B, then the profit made on object A will be nearest to:
A) 42%
B) 47%
C) 45%
D) 45%
Solution:- [Expected time to be taken: 75 to 90 seconds, Level of Difficulty: Moderate to Hard]
Let the original selling price of both A and B be Rs 100. So, the cost price of A (Profit of 20%) = $\frac{5}{6} \times 100 = \frac{250}{3}$ And, Cost price of B (Loss of 10%) = $\frac{10}{9} \times 100 = \frac{1000}{9}$ After an increase in the selling price by some value, the profit on object B is 10%. So, the new selling price = 110% of the cost price of B = $\frac{1000}{9} \times \frac{110}{100} = \frac{1100}{9}$ Profit of A = $\frac{1100}{9} - \frac{250}{3} = \frac{350}{9}$ Profit percentage of A = $\frac{\frac{350}{9}}{\frac{250}{3}} \times 100 = 46.67$% (Nearest to 47%) Hence, the correct answer is option (2).
Q.4) Minu purchased a pair of sunglasses for Rs. 1000 and sold them to Kanu for 20% profit. Then, Kanu sells it back to Minu at a 20% loss. Finally, Minu sells the same pair of sunglasses to Tanu. If the total profit made by Minu from all her transactions is Rs. 500, then the percentage of profit made by Minu when she sold the pair of sunglasses to Tanu is
A) 35.42%
B) 31.25%
C) 52%
D) 52%
Solution:- [Expected time to be taken: 60 to 75 seconds, Level of Difficulty: Moderate]
Initial Cost Price for Minu = 1000 Cost Price to Kanu = 120% of 1000 = 1200 Profit made by Minu = 1200 – 1000 = 200 Again Minu purchased at 80% of 1200 = 960 The total profit made by Manu is 500. So, profit made when she sold it to Tanu = 500 – 200 = 300 Final Selling Price for Minu when sold to Tanu = 960 + 300 = 1260 Profit percent = $\frac{300}{960}$ $\times$ 100 = 31.25%
Hence, the correct answer is option (2).
Q.5) Ankita buys 4 kg cashews, 14 kg peanuts and 6 kg almonds when the cost of 7 kg cashews is the same as that of 30 kg peanuts or 9 kg almonds. She mixes all the three nuts and marks a price for the mixture in order to make a profit of Rs. 1752. She sells 4 kg of the mixture at this marked price and the remaining at a 20% discount on the marked price, thus making a total profit of Rs. 744. Then the amount, in rupees, that she had spent in buying almonds is:
A) 1680
B) 1176
C) 2520
D) 2520
Solution:- [Expected time to be taken: 90 to 120 seconds, Level of Difficulty: Hard]
It is given,7C = 30P = 9A and Ankita bought 4C, 14P and 6A. Let 7C = 30P = 9A = 630k C = 90k, P = 21k, and A = 70k Cost price of 4C, 14P and 6A = 4(90k)+14(21k)+6(70k) = 1074k Marked up price = 1074k + 1752 $\begin{aligned} & \text { S.P }=\frac{1}{6}(1074 k+1752)+\left(\frac{4}{5}\right)\left(\frac{5}{6}\right)(1074 k+1752)=\frac{5}{6}(1074 k+1752) \\ & \text { S.P-C.P }=\text { profit } \\ & 1460-\frac{1074 k}{6}=744 \\ & \frac{1074 k}{6}=716\end{aligned}$ k = 4 Money spent on buying almonds = 420k = 420 × 4 = Rs 1680 The correct answer is Rs. 1680.
Q.6) Amal buys 110 kg of syrup and 120 kg of juice, syrup being 20% less costly than juice, per kg. He sells 10 kg of syrup at 10% profit and 20 kg of juice at 20% profit. Mixing the remaining juice and syrup, Amal sells the mixture at Rs 308.32 per kg and makes an overall profit of 64%. Then, Amal’s cost price for syrup, in rupees per kg, is:
A) 160
B) 180
C) 220
D) 220
Solution:- [Expected time to be taken: 90 to 120 seconds, Level of Difficulty: Hard]
Let the price of juice be Rs. $x$ per kg. Since the cost price of syrup is 20% less than the cost price of juice, the cost price of syrup is $0.8x$ per kg. Total cost price of syrup $= 110 × 0.8x = 88x$ Total cost price of juice $= 120 × x = 120x$ Total cost price $= 88x + 120x = 208x$ Since the overall profit percentage is 64%, Total profit $= 0.64(208x) = 133.12x$ Profit generated by selling 10 kg of syrup which costs Rs $0.8x$ per kg at 10% profit $= 0.1 ×10 ×0.8x = 0.8x$ Profit generated on selling 20 kg of juice which costs Rs $x$ per kg at 20% profit $= 0.2 ×20x = 4x$ The remaining profit $(133.12x - (0.8x + 4x) = 128.32x)$ is generated by selling 100 kg of syrup and 100 kg of juice at Rs 308.32 per kg. The total selling price of 100 kg of syrup and 100 kg of juice is 200 × 308.32 = 2×(30832) The cost price of 100 kg of syrup $= 0.8x ×100 = 80x$ Cost price of 100 kg of juice = $100x$ Total cost price $= 80x + 100x = 180x$ Profit = Selling price – Cost price ⇒ $128.32x = 2×(30832) - 180x$ ⇒ $308.32x = 2×(30832)$ ⇒ $x = 200$ Cost price of syrup per kg = 0.8 × (200) = Rs 160 Hence, the correct answer is option (1).

M/s Deloitte Touche Tohmatsu Limited, one of the top four audit and accounting firms in the world with headquarters at London, UK, and with an operational presence in 153 countries, hires Management Trainees (MT) from all the premier management institutes of India thrice every year, in the months of January, May and September.
Each new group of Management Trainees (MT) have to go through a four month rigorous training schedule, after which they have to pass through a test consisting of a written assessment and a case-analysis. The top hundred ranked Management Trainees (MT) based on the performance in the test are confirmed as Management Executives (ME). The rest are given the opportunity of undergoing the training for four months one more time along with the next batch of Management Trainees (MT) and then passing through the subsequent test consisting of the written assessment and case-analysis. The Management Trainee (MT) who fails to get confirmed as a Management Executive (ME) the second time is fired.
The scatter-graph below depicts the number of Management Trainees (MT) at Deloitte taking the tests from January 2020 till May 2022, and the vis-à-vis hired Management Trainees (MT) at Deloitte who were fired :
It is also known that for the month of September 2019 at Deloitte, 96 hired Management Trainees (MT) failed to be confirmed as a Management Executive (ME) the first time, and that 36 hired Management Trainees (MT) were fired.
Question :
In which test did the minimum number of Management Trainees (MT) get confirmed as a Management Executive (ME) in the second attempt ?
Two friends Moloy and Niloy passed out from the Purulia Institute of Science and Technology with B.Tech degrees in Mechanical Engineering, but even after a year placement was hard to find. So they decided to take the challenge head-on, came down to Kolkata, rented a garage space on Park Street, and having an affinity towards making people enjoy good food, started their firm named 'B.Tech Bread-Omlette Wala'.
They started with three items on the menu. One was the French Toast which could be prepared in 3 minutes. The second was the Egg Tortillas which took 15 minutes to prepare. Any one of Moloy and Niloy could prepare any one of them at a time. The third was the Egg Bhurji with French Fries. This however was prepared on an automated fryer which could prepare 3 servings at a time and took 5 minutes irrespective of the number of servings equal to or below 3. The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected. So one could tend to the preparation of other items while the Egg Bhurji with French Fries were being prepared.
They wanted to serve the orders as early as possible after the order was given. The individual items in any order were served as and when all the items were ready, and the order was then considered closed. None of the items on the menu were prepared in advance in anticipation of future orders.
On the first day, 3 groups of customers came in and ordered at 6.00 pm, 6.10 pm, and 6.13 pm. The first order was for a plate of Egg Tortillas, two plates of French Toast, and three plates of Egg Bhurji with French Fries. The second order was for a plate of French Toast and two plates of Egg Bhurji with French Fries. The third order was for a plate of Egg Tortilla and a plate of Egg Bhurji with French Fries.
On the backdrop of the above information answer the questions given :
Question:
Assuming that the next customer's order could only be attended to when the previous customer's order was closed, at what time would the first customer's order be considered closed ?
