1. What was the selling price of the ring that Tabita bought for $ 840 and sold at a profit of $ 85?

Correct Answer: Correct answer is: (C) $ 925.

Exam Relevance: GMAT, GRE, SAT, ACT

Difficulty: Moderate

Concept notes: The selling price of an item is calculated by adding the profit to the cost price.

Common Mistakes: A common mistake is to confuse the cost price with the selling price or to misinterpret the profit as a percentage rather than an absolute value.

Explanations: To find the selling price, we add the profit to the cost price. The cost price of the ring is $840, and the profit is $85. Therefore, the selling price is calculated as follows: \[ \text{Selling Price} = \text{Cost Price} + \text{Profit} \] \[ \text{Selling Price} = 840 + 85 = 925 \] Thus, the selling price of the ring is $925.

Option Analysis:

Option A: $755 is incorrect because it is less than the cost price and does not account for the profit.
Option B: $840 is incorrect because it is the cost price and does not include the profit.
Option C: $925 is correct because it is the sum of the cost price and the profit.
Option D: $945 is incorrect because it is more than the correct selling price of $925.

2. A trader bought 100 pencils for 40 SAR and then he sold them for 60 SAR. How much profit did he make?

Correct Answer: Correct answer is: (B) 20 SAR.

Exam Relevance: GMAT, GRE, SAT, ACT

Difficulty: Easy

Concept notes: Profit is calculated as the difference between the selling price and the cost price.

Common Mistakes: A common mistake is to confuse profit with the selling price or cost price alone.

Explanations: The trader bought 100 pencils for 40 SAR and sold them for 60 SAR. To find the profit, we subtract the cost price from the selling price: \[ \text{Profit} = \text{Selling Price} - \text{Cost Price} \] \[ \text{Profit} = 60 \, \text{SAR} - 40 \, \text{SAR} \] \[ \text{Profit} = 20 \, \text{SAR} \]

Option Analysis:

Option A: 10 SAR is incorrect because it does not account for the full difference between the selling price and the cost price.
Option B: 20 SAR is correct as it accurately represents the profit made by the trader.
Option C: 30 SAR is incorrect because it overestimates the profit.
Option D: 40 SAR is incorrect because it is the cost price, not the profit.

3. Bob bought a cycle for Rs. 3725. After using it for few months he sold it for a loss of Rs. 589. Find the selling price of the cycle.

Correct Answer: Correct answer is: (B) Rs. 3136.

Exam Relevance: CAT, GMAT, GRE, SAT

Difficulty: Easy

Concept notes: The concept of loss in profit and loss calculations involves subtracting the loss amount from the cost price to find the selling price.

Common Mistakes: A common mistake is to add the loss to the cost price instead of subtracting it.

Explanations: The cost price of the cycle is Rs. 3725. Bob sold it at a loss of Rs. 589. To find the selling price, we subtract the loss from the cost price: \[ \text{Selling Price} = \text{Cost Price} - \text{Loss} \] \[ \text{Selling Price} = 3725 - 589 = 3136 \] Thus, the selling price of the cycle is Rs. 3136.

Option Analysis:

Option A: Rs. 3163 is incorrect because it does not match the calculation of cost price minus loss.
Option B: Rs. 3136 is correct as it matches the calculation of cost price minus loss.
Option C: Rs. 3236 is incorrect because it does not match the calculation of cost price minus loss.
Option D: None of these is incorrect because Rs. 3136 is the correct answer.

4. Paul made a profit of $ 45.45 by selling his bicycle for $ 90.65. What was the cost price of his bicycle?

Correct Answer: Correct answer is: (A) $ 45.20.

Exam Relevance: GMAT, GRE, SAT, ACT

Difficulty: Easy

Concept notes: The cost price of an item can be calculated using the formula: Cost Price = Selling Price - Profit.

Common Mistakes: A common mistake is to add the profit to the selling price instead of subtracting it.

Explanations: To find the cost price, we use the formula: Cost Price = Selling Price - Profit. Given: Selling Price = $90.65 Profit = $45.45 Cost Price = $90.65 - $45.45 = $45.20

Option Analysis:

Option A: Correct. The cost price is $45.20.
Option B: Incorrect. $50.20 is not the correct cost price.
Option C: Incorrect. $55.20 is not the correct cost price.
Option D: Incorrect. $60.20 is not the correct cost price.

5. If the selling price is Rs. 1500 and cost price is Rs.3599 then the loss is .....

Correct Answer: Correct answer is: (B) 2099.

Exam Relevance: CAT, GMAT, GRE, SAT

Difficulty: Moderate

Concept notes: In profit and loss calculations, loss is determined by subtracting the selling price from the cost price.

Common Mistakes: A common mistake is to subtract the cost price from the selling price, which would give a profit instead of a loss.

Explanations: To find the loss, we use the formula: Loss = Cost Price - Selling Price Given: Cost Price = Rs. 3599 Selling Price = Rs. 1500 Loss = 3599 - 1500 = 2099

Option Analysis:

Option A: 2000 is incorrect because it does not match the calculated loss.
Option B: 2099 is the correct loss calculated using the formula.
Option C: 299 is incorrect because it does not match the calculated loss.
Option D: 2990 is incorrect because it does not match the calculated loss.

6. When the selling price of a TV is '18,700, the shopkeeper incurred a loss of 15%. What should be the selling price of that TV to gain 15%?

Correct Answer: Correct answer is: (A) ' 25,300.

Exam Relevance: CAT, GMAT, GRE, SAT, Competitive Exams

Difficulty: Moderate

Concept notes: The concept involves calculating the cost price from the selling price and loss percentage, and then determining the selling price for a desired profit percentage.

Common Mistakes: A common mistake is to incorrectly calculate the cost price or to mix up the profit and loss percentages.

Explanations: 1. First, we need to find the cost price (CP) of the TV. Given that the selling price (SP) is '18,700 and the loss is 15%, we can use the formula: \[ \text{CP} = \frac{\text{SP}}{1 - \text{Loss Percentage}} \] Substituting the values: \[ \text{CP} = \frac{18,700}{1 - 0.15} = \frac{18,700}{0.85} = 22,000 \] 2. Next, we need to find the selling price (SP) to gain 15%. We use the formula: \[ \text{SP} = \text{CP} \times (1 + \text{Profit Percentage}) \] Substituting the values: \[ \text{SP} = 22,000 \times (1 + 0.15) = 22,000 \times 1.15 = 25,300 \] Thus, the selling price to gain 15% is '25,300.

Option Analysis:

Option A: Correct. The calculated selling price to gain 15% is '25,300.
Option B: Incorrect. This value is not derived from the correct cost price and profit percentage.
Option C: Incorrect. This value is not derived from the correct cost price and profit percentage.
Option D: Incorrect. This value is not derived from the correct cost price and profit percentage.

7. The formula for loss is-

Correct Answer: Correct answer is: (B) CP-SP.

Exam Relevance: CAT, GMAT, GRE, SAT, Competitive Exams

Difficulty: Easy

Concept notes: In profit and loss calculations, the loss is determined when the cost price (CP) is greater than the selling price (SP). The formula for loss is the difference between the cost price and the selling price.

Common Mistakes: A common mistake is to confuse the formula for loss with the formula for profit, which is SP - CP.

Explanations: The loss is calculated as the cost price minus the selling price (CP - SP). This formula reflects the amount by which the cost price exceeds the selling price, indicating a financial loss.

Option Analysis:

Option A: SP - CP is the formula for profit, not loss.
Option B: CP - SP is the correct formula for loss.
Option C: Both options cannot be correct as they represent different financial outcomes (profit and loss).
Option D: None of the options is incorrect because one of the options (B) is correct.

8. When a profit happens?

Correct Answer: Correct answer is: (C) CP

Exam Relevance: CAT, GMAT, GRE, SAT

Difficulty: Easy

Concept notes: In profit and loss, profit occurs when the selling price (SP) is greater than the cost price (CP).

Common Mistakes: A common mistake is to confuse the conditions for profit and loss. Profit happens when SP > CP, not the other way around.

Explanations: Profit is defined as the difference between the selling price and the cost price when the selling price is higher than the cost price. Therefore, the condition for profit is SP > CP, which is the opposite of the given option C (CP < SP).

Option Analysis:

Option A: CP > SP. This condition represents a loss, not a profit.
Option B: SP = CP. This condition represents no profit and no loss, which is a break-even situation.
Option C: CP < SP. This condition represents a profit, as the selling price is greater than the cost price.
Option D: None of the above. This is incorrect because option C correctly represents the condition for profit.

9. Shankar makes and sells bracelets. It costs her Rs 3 in materials for each bracelet she makes. If he makes and sells 20 bracelets for Rs 14 each, what is his profit?

Correct Answer: Correct answer is: (C) Rs 220.

Exam Relevance: GMAT, GRE, CAT, SAT

Difficulty: Moderate

Concept notes: Profit is calculated as the total revenue minus the total cost. The total revenue is the selling price per bracelet multiplied by the number of bracelets sold. The total cost is the cost per bracelet multiplied by the number of bracelets made.

Common Mistakes: A common mistake is to forget to subtract the total cost from the total revenue, leading to an incorrect calculation of profit.

Explanations: To find the profit, we need to calculate the total revenue and the total cost. The total revenue is the selling price per bracelet multiplied by the number of bracelets sold: \[ \text{Total Revenue} = 20 \times 14 = 280 \text{ Rs} \] The total cost is the cost per bracelet multiplied by the number of bracelets made: \[ \text{Total Cost} = 20 \times 3 = 60 \text{ Rs} \] The profit is the total revenue minus the total cost: \[ \text{Profit} = 280 \text{ Rs} - 60 \text{ Rs} = 220 \text{ Rs} \]

Option Analysis:

Option A: Rs 280. This is the total revenue, not the profit.
Option B: Rs 60. This is the total cost, not the profit.
Option C: Rs 220. This is the correct profit.
Option D: Not Here. This is not the correct answer.

10. A vendor buys oranges at Rs 26 per dozen and sells them at 5 for Rs 13. Find his gain percent.

Correct Answer: Correct answer is: (C) 20.3%.

Exam Relevance: CAT, GMAT, GRE, SAT

Difficulty: Moderate

Concept notes: The concept of profit and loss involves calculating the cost price (CP), selling price (SP), and then determining the gain or loss percentage based on these values.

Common Mistakes: A common mistake is not converting the quantities to a common unit (e.g., per dozen or per piece) before calculating the cost price and selling price.

Explanations: 1. Calculate the cost price (CP) per orange: - The vendor buys oranges at Rs 26 per dozen. - Therefore, CP per orange = Rs 26 / 12 = Rs 2.1667. 2. Calculate the selling price (SP) per orange: - The vendor sells 5 oranges for Rs 13. - Therefore, SP per orange = Rs 13 / 5 = Rs 2.60. 3. Calculate the gain per orange: - Gain per orange = SP per orange - CP per orange = Rs 2.60 - Rs 2.1667 = Rs 0.4333. 4. Calculate the gain percentage: - Gain percentage = (Gain per orange / CP per orange) * 100 = (0.4333 / 2.1667) * 100 ≈ 20.3%. Thus, the gain percentage is 20.3%.

Option Analysis:

Option A: 59% is incorrect because it overestimates the gain percentage.
Option B: 17% is incorrect because it underestimates the gain percentage.
Option C: 20.3% is the correct gain percentage as calculated.
Option D: 15.4% is incorrect because it underestimates the gain percentage.
