**Text Explanation** :

Let the selling price be Rs. x

Cost price of item sold to A = x/1.2

Cost price of item sold to B = x/0.9

To make calculations easier assume x = 108 (LCM of 12 and 9)

∴ Cost price of item sold to A = x/1.2 = 90

∴ Cost price of item sold to B = x/0.9 = 120

Now, selling price is increased such that a profit of 10% is made for item B.

⇒ New selling price = 120 × 1.1 = Rs. 132

∴ For A, cost price = Rs. 90 and selling price = Rs. 132.

⇒ % profit for A = $\frac{(132-90)}{90}$ × 100% = 46.66% ≈ 47%.

Hence, option (d).

**Text Explanation** :

Minu purchases a pair of sunglasses at Rs.1000 and sells to Kanu at 20% profit. Then, Kanu sells it back to Minu at 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

Initially cost price of Minu = Rs. 1000

Minu sells it to Kanu at 20% profit i.e., at Rs. 1000 + 200 = Rs. 1200

Profit earned by Minu = Rs. 200

Now, Kanu sells it back to Minu at 20% loss on 1200 i.e., at 1200 + 240 = Rs. 960

Now, let Minu sells it to Tanu at a profit of x.

∴ 200 + x = 500

⇒ x = 300

∴ Minu earns 300 profit by selling the sunglasses to Tanu, hence her profit % = 300/960 × 100% = 31.25%

Hence, option (b).

Jayant bought a certain number of white shirts at the rate of Rs 1000 per piece and a certain number of blue shirts at the rate of Rs 1125 per piece. For each shirt, he then set a fixed market price which was 25% higher than the average cost of all the shirts. He sold all the shirts at a discount of 10% and made a total profit of Rs 51000. If he bought both colors of shirts, then the maximum possible total number of shirts that he could have bought is

Answer: 407

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the number of white and blue shirts bought is 'w' and 'b' respectively.

Total cost price = 1000w + 1125b

⇒ Average cost price/shirt = $\frac{1000\mathrm{w}+1125\mathrm{b}}{\mathrm{w}+\mathrm{b}}$

⇒ Average marked price/shirt = $\frac{1000\mathrm{w}+1125\mathrm{b}}{\mathrm{w}+\mathrm{b}}\times 1.25$

⇒ Average sellingprice/shirt = $\frac{1000\mathrm{w}+1125\mathrm{b}}{\mathrm{w}+\mathrm{b}}\times 1.25\times 0.9$

⇒ Total selling price = (1000w + 1125b) × 1.25 × 0.9

∴ Profit = 51000 = (1000w + 1125b) × 1.25 × 0.9 - (1000w + 1125b)

⇒ 51000 = (1000w + 1125b) × (1.25 × 0.9 - 1)

⇒ 51000 = (1000w + 1125b) × (0.125)

⇒ 1000w + 1125b = 408000

⇒ 40w + 45b = 16320

⇒ 8w + 9b = 3264

w + b will be maximum when we maximum the variable with least coefficiency and minimise the variable with highest coefficient.

Least possible value of of b cannot be 0 as at least one shirt of each type is bought. Hence, the next least possible value of b possible is 8.

∴ b = 8 and w = 399

∴ Highest possible value of w + b = 399 + 8 = 407

Hence, 407.

**Text Explanation** :

The merchange earns profit due to increase in price and due to cheating (quantity) while buying and selling.

multiplication factor for price: 110/100 × 0.95

multiplication factor for quantity: while buying = 105/100

while selling = 100/95

overall multiplication factor for quantity: 105/100 × 100/95 = 105/95

⇒ overall multiplication factor (including price and quantity) = 110/100 × 0.95 × 105/95 = 11/10 × 105/100 = 1.155

∴ overal % profit = (1.155 - 1) × 100% = 15.5%

Hence, option (c).

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 ₹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 ₹744.

- (a)
1176

- (b)
1680

- (c)
2520

- (d)
1440

Answer: Option B

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the price of a kg of peanuts, cashews and almonds is Rs. p, c and a.

Given, 7c = 30p = 9a

⇒ c : p : a = 90 : 21 : 70

Ankita mixes 4 kg cashews, 14 kg peanuts and 6 kg almonds, i.e., total 24 kgs.

Total cost price of the mixture = 4 × 90x + 14 × 21x + 6 × 70x = 1074x.

Cost price/kg = 44.75x/kg

She plans to sells this 24 kg mixture for a Profit of Rs. 1752 i.e, at a profit of 1752/24 = Rs. 73/kg.

She sells 4 kg of this mixture at the original selling price and hence earns a profit of 4 × 73 = Rs. 292.

Total profit she actually earns is Rs. 744.

⇒ Profit earned on remaining 20 kgs = 744 – 292 = Rs. 452.

⇒ Profit originally planned on remaining 20 kgs = 20 × 73 = Rs. 1460.

Cost of this 20 kg = 20 × 44.75x = 895x

⇒ (895x + 1460) × 0.8 = 895x + 452

⇒ 1460 × 0.8 – 452 = 895x × 0.2

⇒ 716 = 179x

⇒ x = 4

∴ Price of 6 kg of almonds = 6 × 70 × 4 = 1680

Hence, option (b).

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 ₹ 308.32 per kg and makes an overall profit of 64%. Then, Amal’s cost price for syrup, in Rupees per kg, is

Answer: 160

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the cost price of juice be Rs. 10x/kg, hence cost price of syrup = 8x/kg

10 kg syrup is sold at 10% profit i.e., at 8.8x/kg.

∴ Total selling price = Rs. 88x

20 kg of juice is sold at 20% profit i.e., at 12x/kg

∴ Total selling price = Rs. 240x

Remaining (110 + 120 – 30 =) 200 kg at Rs. 308.32/kg.

Total cost price of the mixture = 110 × 8x + 120 × 10x = 2080x

⇒ 2080x × 1.64 = 88x + 240x + 308.32 × 200

⇒ 2080x × 1.64 - 328x = 308.32 × 200

⇒ 3083.2x = 308.32 × 200

⇒ x = 20

Cost price of syrup = 8x = 160/kg.

Hence, 160.

Answer: 1000

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the total number of pens Amal bought = x

Also, let the wage of the employee = w

∴ Amal’s total cost price = 8x + w

Total selling price of the first 100 pen = 100 × 12 = 1200

**Case 1**: The remaining pen when each is sold at Rs. 11

Total selling price of the remaining pen = (x - 100) × 11

⇒ 1200 + 11(x - 100) = 8x + w + 300

⇒ 3x - 200 = w …(1)

**Case 2**: The remaining pen when each is sold at Rs. 9

Total selling price of the remaining pen = (x - 100) × 9

⇒ 1200 + 9(x - 100) = 8x + w - 300

⇒ x + 600 = w …(2)

Solving (1) and (2) we get

x = 400 and w = 1000.

Hence, 1000.

- (a)
692

- (b)
688

- (c)
675

- (d)
653

Answer: Option B

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let 2, 3, 5 kgs is bought of each variety respectively.

∴ Total quantity bought = 2 + 3 + 5 = 10 kgs

Total cost of tea = 2 × 800 + 3 × 500 + 5 × 300 = 4600.

Profit on total quantity = 50%

∴ Total selling price for 10 kg tea = 4600 × 1.5 = 6900.

Selling price for 1/6^{th} of 10 kg tea = 10/6 × 700 = 7000/6

⇒ Selling price for remaining 50/6 kg tea = 6900 – 7000/6 = 34400/6

∴ Selling price per kg for the remaining tea = 34400/6 ÷ 50/6 = 688

Hence, option (b).

**Text Explanation** :

Let the price of desktop be Rs. d, and laptop be Rs. (50,000 - d)

Total profit = 2% of 50,000 = Rs. 1,000

⇒ 1000 = 20% of d - 10% of (50000 - d)

⇒ 100000 = 20d - 500000 + 10d

⇒ 30d = 6,00,000

⇒ d = 20,000

Hence, 20000.

- (a)
50

- (b)
54

- (c)
60

- (d)
55

Answer: Option A

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the cost price be c and marked price be m. Total selling price for 12 toys = Rs. 12c.

Anil sells 8 toys at 20% discount. Hence, total selling price for 8 toys = 8 × 0.8m = 6.4m

He then sells 4 toys at further 25% discount. Hence, total selling price for 8 toys = 4 × 0.75 × 0.8m = 2.4m

Given, 6.4m + 2.4m = 2112

⇒ m = 240

Now, he earns an overall profit of 10%

∴ 12c × 1.1 = 2112

⇒ c = 160

∴ With no discounts his profit % = (240 - 160)/160 × 100 = 50%

Hence, option (a).

- (a)
25

- (b)
35

- (c)
22

- (d)
31

Answer: Option A

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the cost price of sugar be Rs. 100/kg and marked price will be = Rs. 120/kg

∴ Total cost for the man = 35 × 100 = Rs. 3500

He earns 15% profit on this, hence total selling price = 3500 × 1.15 = Rs. 4025

Total Selling price for 5 kg sugar = 5 × 120 = 600

Total Selling price for 15 kg sugar = 15 × 120 × 0.9 = 1620

Total Selling price for 3 kg sugar = 3 × 0 = 0

Total Selling price for remaining 12 kg sugar = 12 × 120(1 + p%)

∴ 4025 = 600 + 1620 + 0 + 1440(1 + p%)

⇒ 1805 = 1440(1 + p%)

⇒ 1 + p% ≈ 1.25

⇒ p = 25%

Hence, option (a).

**Text Explanation** :

The Shopkeeper procures the table at price 'p'

He gains 20% on the transaction with Amal

So, Amal buys the table at '1.2p'

Amal sells athe table at 30% profit,

So, the Selling Price of Amal = 1.3 × 1.2p = 1.56p

⇒ x = 1.56p

The Shopkeeper loses 20% on the transaction with Asim

So, Asim buys the table at '0.8p'

Asim sells the table at 30% loss,

So, the Selling Price of Asim = 0.7 * 0.8p = 0.56p

⇒ y = 0.56p

(x - y)/p = (1.56p - 0.56p)/p = 1.

- (a)
86

- (b)
84

- (c)
98

- (d)
96

Answer: Option D

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

**Wholesaler:**

Assume that the wholesaler bought peanut at Rs. X per kg.

∴ Cost price of walnuts = Rs. 3X per kg

The wholesaler sold peanuts at Rs. 1.1X per kg and walnuts at Rs. 3.6X per kg.

Total cost of 8 kg peanuts and 16 kg walnuts for the shopkeeper = 8 × 1.1X + 16 × 3.6X = 66.4X

∴ Total cost price for Shopkeeper = 66.4X

**Shopkeeper**:

Shopkeeper's overall profit was 25%

∴ Shopkeeper's revenue = 66.4X × 1.25

He sold (8 – 3 =) 5 kg peanuts and (16 – 5 =) 11 kg walnuts after mixing at Rs. 166 per kg

⇒ 66.4X × 1.25 = 16 × 166

⇒ X = 32

Cost price of walnuts for the wholesaler = 3 × 32 = Rs. 96

Let cost of tea A and B be a and b respectively.

If 3 kg of tea A is mixed with 2 kg of tea B, (3a + 2b) × 1.1 = 40× 5 = 200

If 2 kg of tea A is mixed with 3 kg of tea B, (2a + 3b) × 1.05 = 40× 5 = 200

Therefore,

(3a + 2b) × 1.1 = (2a + 3b) × 1.05

∴ 3.3a + 2.2b = 2.1a + 3.15b

∴ a/b = 19/24

If the trader sells the entire mixture for Rs. 264 and makes a profit of 10%, then the highest possible cost of paint B, in Rs. per litre, is

- (a)
20

- (b)
26

- (c)
16

- (d)
22

Answer: Option A

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the 10 litres of mixture has ‘Y’ litres of A and (10 – Y) litres of B. Let cost of paint B be Rs. X and that of A be Rs. (X + 8).

We know that, Y ≥ (10 – Y) ⇒ Y ≥ 5

The trader makes 10% profit by selling this mixture at Rs. 264.

∴ Cost price of the mixture = $\frac{264}{1.1}$ = Rs. 240

∴ (X + 8) × Y + (10 – Y) × X = 240

∴ 10X + 8Y = 240

∴ X = 24 – 0.8Y

For maximum value of X, we need to consider minimum value of Y.

∴ X = 24 – (0.8 × 5) = Rs. 20

Hence, option (a).

If Fatima sells 60 identical toys at a 40% discount on the printed price, then she makes 20% profit. Ten of these toys are destroyed in fire. While selling the rest, how much discount should be given on the printed price so that she can make the same amount of profit?

- (a)
30%

- (b)
25%

- (c)
24%

- (d)
28%

Answer: Option D

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let the printed price be p.

If 40% discount is given, selling price = 0.6 × 60p = 36 p

20% profit is then made.

Total cost price = 36p/1.2 = 30p.

Ten toys are destroyed in the fire.

The remaining toys are sold at a price such that the same amount of profit is made as in the conditional case.

Profit made on remaining toys = 6p

Total selling price of remaining toys = 36p

Discount that should be given = 50p – 36p = 14p

Discount% = $\frac{14p}{50p}\times 100$% = 28%

Hence, option (d).

**Text Explanation** :

Lets the manufacturers C.P. be x

As he sells it to the wholesaler at 10% profit, his S.P will be 1.1x

Now 110 is also the wholesaler’s C.P. Further, as the wholesaler sells it to a retailer at 30%, profit, his S.P will be

$\frac{130}{100}$ × 1.1x = 1.43x

Now 1.43x also the retailers C.P

As the retailer sells it to the customer at

50% profit, S.P. will be $\frac{150}{100}$ × 1.43x or 2.145x

The price paid by the customer is Rs. 4290

⇒ 2.145x = 4290

⇒ x = 2000

So Rs. 2000 is the manufacturer’s cost

Hence, option (c).

Mayank buys some candies for Rs 15 a dozen and an equal number of different candies for Rs 12 a dozen. He sells all for Rs 16.50 a dozen and makes a profit of Rs 150. How many dozens of candies did he buy altogether?

- (a)
50

- (b)
30

- (c)
25

- (d)
45

Answer: Option A

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Supposing Mayank buys ‘x’ dozen candies at Rs. 15 per dozen and another ‘x’ dozen candies at Rs. 12 per dozen.

Total C.P =15(x) + 12(x) per dozen.

Now he sells these ‘x + x’ or ‘2x’ dozen candies at Rs. 16.50 per dozen.

So total S.P = 16.50 × 2x = 33x

Profit = 33x -27x = 6x

Now 6x = 150 or x = 25

As Mayank buys ‘2x’ dozen candies, number of dozens of candies bought by him

= 2 × 25 or 50

Hence, option (a).

A leather factory produces two kinds of bags, standard and deluxe. The profit margin is Rs. 20 on a standard bag and Rs. 30 on a deluxe bag. Every bag must be processed on machine A and on machine B. The processing times per bag on the two machines are as follows:

The total time available on machine A is 700 hours and on machine B is 1250 hours. Among the following production plans, which one meets the machine availability constraints and maximizes the profit?

- (a)
Standard 75 bags, Deluxe 80 bags

- (b)
Standard 100 bags, Deluxe 60 bags

- (c)
Standard 50 bags, Deluxe 100 bags

- (d)
Standard 60 bags, Deluxe 90 bags

Answer: Option A

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Total time available is 700 hrs on machine A and 1250 hrs on machine B.

Let the number of Standard Bags be s and the number of Deluxe Bags be d.

Here we have to maximize the profit margin i.e. 20s + 30d, subject to the constraints,

4s + 5d ≤ 700 and 6s + 10d ≤ 1250

Now consider options.

1. s = 75 and d = 80

∴ The profit = 75 × 20 + 30 × 80 = 3900

4s + 5d = 700 and 6s + 10d = 1250

∴ the constraints are satisfied.

2. s = 100 and d = 60

∴ The profit = 100 × 20 + 60 × 30 = 3800

The profit is less than in option 1.

∴ Option 2 is not the answer.

3. s = 50 and d = 100

∴ The profit = 50 × 20 + 100 × 30 = 4000

4s + 5d = 700 and 6s + 10d = 1300

∴ The second constraint is not satisfied.

∴ Option 3 cannot be the answer.

4. s = 60 and d = 90

∴ The profit = 60 × 20 + 90 × 30 = 3900

4s + 5d = 690 and 6s + 10d = 1260

∴ The second constraint is not satisfied.

∴ Option 4 cannot be the answer.

As only option 1 satisfies the constraints and also maximizes the profit, option 1 is the answer.

Hence, option (a).

A dress was initially listed at a price that would have fetched the store a profit of 20% on the wholesale cost. What was the wholesale cost of the dress?

A. After reducing the listed price by 10% the dress was sold for a net profit of 10 dollars.

B. The dress was sold for 50 dollars.

- (a)
1

- (b)
2

- (c)
3

- (d)
4

Answer: Option A

**Text Explanation** :

Let 100x be the wholesale cost of the dress.

∴ List price of the dress = 120x

**Consider statement A:**

Selling Price = 0.9 × List Price = 0.9 × 120x = 108x

Now, Selling Price – Cost Price = Profit

∴ (108x) − (100x) = 10

∴ x = 10/8

∴ Wholesale Cost = 100x = Rs. 125

∴ Statement A alone is sufficient.

**Consider statement B:**

This gives the selling price of the dress but it is not mentioned whether any discount is provided on the list price or not.

∴ Statement B alone is not sufficient.

Hence, option (a).

- The sales price per share was 1.05 times that of its purchase price.
- The number of shares purchased was 100.

- (a)
1

- (b)
2

**Text Explanation** :

From Statement A

The cost of buying the shares for Harshad is

CP + 0.01 CP = 1.01 CP

The cost of selling the shares for Harshad is

SP – 0.01 SP = 0.99 SP

∴ Profit = Cost of selling – Cost of buying

= 0.99 SP – 1.01 CP

∵ SP = 1.05 CP

Profit = (0.99 × 1.05 CP) – 1.01 CP

= 0.0295 CP

∴ Profit earned per rupee spent on buying the shares is Rs 0.0295.

From the number of shares given in the statement B, we cannot conclude anything.

Hence, option (a).

**Answer the next 2 questions based on the following information.**

A company purchases components A and B from Germany and USA respectively. A and B form 30% and 50% of the total production cost. Current gain is 20%. Due to change in the international scenario, cost of the German mark increased by 30% and that of USA dollar increased by 22%. Due to market conditions, the selling price cannot be increased beyond 10%.

**CAT 1998 QA | Arithmetic - Profit & Loss CAT Question**

What is the maximum current gain possible?

- (a)
10%

- (b)
12.5%

- (c)
0%

- (d)
7.5%

Answer: Option A

Join our Telegram Group for CAT Preparation.

**Text Explanation** :

Let CP = 100

Current gain = 20

⇒ SP = 120

CP = Cost of A + Cost of B + other

= 30% + 50% + 20%

Since cost of German mark (A) increase by 30%

New cost of A = 30 + 30% of 30 = 39

Similarly

New cost of B = 50 + 22% of 50 = 61

New CP = 39 + 61 + 20 = 120

New SP = 120 + 10% of 120 = 132

Maximum profit = $\frac{12}{20}=10\%$
