21. A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. His profit percent is?

5%

10%

15%

20%

The trader is mixing two varieties of rice with different prices to create a new mixture. The cost price of the first variety of rice is Rs. 20 per kg and the cost price of the second variety is Rs. 36 per kg. The trader then sells the mixture at Rs. 30 per kg. To calculate the profit percentage, we need to compare the selling price with the cost price.

The cost price of the mixture can be calculated by finding the weighted average of the two varieties of rice. The total weight of the mixture is 26 kg + 30 kg = 56 kg.

The cost price of the first variety of rice is 26 kg * Rs. 20 per kg = Rs. 520.
The cost price of the second variety of rice is 30 kg * Rs. 36 per kg = Rs. 1080.

The total cost price of the mixture is Rs. 520 + Rs. 1080 = Rs. 1600.

The selling price of the mixture is 56 kg * Rs. 30 per kg = Rs. 1680.

The profit made by the trader is Rs. 1680 - Rs. 1600 = Rs. 80.

The profit percentage is (80/1600) * 100 = 5%.

Therefore, the correct answer is 5%.

Explanation

The trader is mixing two varieties of rice with different prices to create a new mixture. The cost price of the first variety of rice is Rs. 20 per kg and the cost price of the second variety is Rs. 36 per kg. The trader then sells the mixture at Rs. 30 per kg. To calculate the profit percentage, we need to compare the selling price with the cost price.

The cost price of the mixture can be calculated by finding the weighted average of the two varieties of rice. The total weight of the mixture is 26 kg + 30 kg = 56 kg.

The cost price of the first variety of rice is 26 kg * Rs. 20 per kg = Rs. 520.
The cost price of the second variety of rice is 30 kg * Rs. 36 per kg = Rs. 1080.

The total cost price of the mixture is Rs. 520 + Rs. 1080 = Rs. 1600.

The selling price of the mixture is 56 kg * Rs. 30 per kg = Rs. 1680.

The profit made by the trader is Rs. 1680 - Rs. 1600 = Rs. 80.

The profit percentage is (80/1600) * 100 = 5%.

Therefore, the correct answer is 5%.

10 %

15 %

20 %

25 %

The fruit seller purchases 3 oranges for Rs. 5, which means the cost price of each orange is Rs. 5/3. He sells 2 oranges for Rs. 4, which means the selling price of each orange is Rs. 2. Therefore, the profit per orange is Rs. 2 - Rs. 5/3 = Rs. 1/3. The profit percentage can be calculated as (profit per orange / cost price per orange) * 100 = (1/3 / 5/3) * 100 = 20%. Hence, the profit in the transaction is 20%.

Explanation

The fruit seller purchases 3 oranges for Rs. 5, which means the cost price of each orange is Rs. 5/3. He sells 2 oranges for Rs. 4, which means the selling price of each orange is Rs. 2. Therefore, the profit per orange is Rs. 2 - Rs. 5/3 = Rs. 1/3. The profit percentage can be calculated as (profit per orange / cost price per orange) * 100 = (1/3 / 5/3) * 100 = 20%. Hence, the profit in the transaction is 20%.

23. If the cost price of 20 articles is equal to the selling price of 25 articles, what is the % profit or loss made by the merchant?

25% loss

25% profit

20% loss

20% profit

Solution:

Let the cost price of 1 article be Rs 1.
Therefore, cost price of 20 articles = 20 * 1 = Rs 20

The selling price of 25 articles = cost price of 20 articles = Rs 20.

Now, we know the selling price of 25 articles. Let us find the cost price of 25 articles.

Cost price of 25 articles = 25 * 1 = Rs 25.

Therefore, profit made on sale of 25 articles = Selling price of 25 articles - cost price of 25 articles

= 20 - 25 = - Rs 5.

As the profit is in the negative, the merchant has made a loss of Rs 5.

Therefore, % loss = (Loss/Cost Price) * 100

% loss = [ -5/25 ] *100 = 20% loss.

Explanation

Solution:

Let the cost price of 1 article be Rs 1.
Therefore, cost price of 20 articles = 20 * 1 = Rs 20

The selling price of 25 articles = cost price of 20 articles = Rs 20.

Now, we know the selling price of 25 articles. Let us find the cost price of 25 articles.

Cost price of 25 articles = 25 * 1 = Rs 25.

Therefore, profit made on sale of 25 articles = Selling price of 25 articles - cost price of 25 articles

= 20 - 25 = - Rs 5.

As the profit is in the negative, the merchant has made a loss of Rs 5.

Therefore, % loss = (Loss/Cost Price) * 100

% loss = [ -5/25 ] *100 = 20% loss.

24. What is a single discount equivalent to a discount series of 10% and 20%?

A single discount equivalent to a discount series of 10% and 20% would be 28%. This means that if an item originally costs $100, applying a 28% discount would result in a final price of $72. The 10% discount would reduce the price to $90, and then the additional 20% discount would further reduce it to $72. Therefore, a single discount of 28% is equivalent to the discount series of 10% and 20%.

Explanation

A single discount equivalent to a discount series of 10% and 20% would be 28%. This means that if an item originally costs $100, applying a 28% discount would result in a final price of $72. The 10% discount would reduce the price to $90, and then the additional 20% discount would further reduce it to $72. Therefore, a single discount of 28% is equivalent to the discount series of 10% and 20%.

25. A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. His profit percent is?

5%

10%

15%

20%

The trader mixes two varieties of rice at different prices to create a mixture. The cost price of the first variety is Rs. 20 per kg and the cost price of the second variety is Rs. 36 per kg. The trader then sells the mixture at Rs. 30 per kg. To find the profit percentage, we need to compare the selling price to the cost price. Here, the selling price is greater than the cost price, indicating a profit. The profit percentage can be calculated using the formula: (Profit/Cost Price) * 100. In this case, the profit percentage is 5%.

27. 100 oranges are bought at the rate of Rs. 350 and sold at the rate of Rs. 48 per dozen. The percentage of profit or loss is?

100/3 profit

100/7 loss

100/7 profit

100/3 loss

The percentage of profit or loss is 100/7 profit. This can be calculated by finding the difference between the selling price and the cost price and then dividing it by the cost price. In this case, the selling price of 100 oranges is Rs. 48 per dozen, which is equivalent to Rs. 4 per orange. The cost price of 100 oranges is Rs. 350. Therefore, the profit is Rs. (4 * 100) - 350 = Rs. 50. To find the percentage of profit, we divide the profit by the cost price and multiply by 100: (50/350) * 100 = 100/7 profit.

Explanation

The percentage of profit or loss is 100/7 profit. This can be calculated by finding the difference between the selling price and the cost price and then dividing it by the cost price. In this case, the selling price of 100 oranges is Rs. 48 per dozen, which is equivalent to Rs. 4 per orange. The cost price of 100 oranges is Rs. 350. Therefore, the profit is Rs. (4 * 100) - 350 = Rs. 50. To find the percentage of profit, we divide the profit by the cost price and multiply by 100: (50/350) * 100 = 100/7 profit.

28. The price of the jewel,passing through three hands,rises on the whole by65%.if the first and the second sellers 20%and25% profit respectively find the percentage profit earned by the third seller?

10%

20%

25%

5%

The price of the jewel increases by 65% in total. The first seller makes a profit of 20% and the second seller makes a profit of 25%. To find the profit earned by the third seller, we need to subtract the profits made by the first two sellers from the total increase in price.

Let's assume the original price of the jewel is 100.

The first seller sells it for 120 (100 + 20% profit)
The second seller sells it for 150 (120 + 25% profit)

The total increase in price is 50 (150 - 100)

Therefore, the profit earned by the third seller is 10% (50/500 * 100).

Explanation

The price of the jewel increases by 65% in total. The first seller makes a profit of 20% and the second seller makes a profit of 25%. To find the profit earned by the third seller, we need to subtract the profits made by the first two sellers from the total increase in price.

Let's assume the original price of the jewel is 100.

The first seller sells it for 120 (100 + 20% profit)
The second seller sells it for 150 (120 + 25% profit)

The total increase in price is 50 (150 - 100)

Therefore, the profit earned by the third seller is 10% (50/500 * 100).

29. A fruit seller purchases oranges at the rate of 3 for Rs.5 and sells them at 2 for Rs.4. His profit in the transaction is?

10 %

15 %

20 %

25 %

The fruit seller purchases 3 oranges for Rs. 5, which means the cost price of one orange is Rs. 5/3. He sells 2 oranges for Rs. 4, so the selling price of one orange is Rs. 2. The profit is calculated by subtracting the cost price from the selling price, which is Rs. 2 - Rs. 5/3 = Rs. 1/3. To find the profit percentage, we divide the profit by the cost price and multiply by 100: (1/3) / (5/3) * 100 = 20%. Therefore, the profit percentage in the transaction is 20%.

Explanation

The fruit seller purchases 3 oranges for Rs. 5, which means the cost price of one orange is Rs. 5/3. He sells 2 oranges for Rs. 4, so the selling price of one orange is Rs. 2. The profit is calculated by subtracting the cost price from the selling price, which is Rs. 2 - Rs. 5/3 = Rs. 1/3. To find the profit percentage, we divide the profit by the cost price and multiply by 100: (1/3) / (5/3) * 100 = 20%. Therefore, the profit percentage in the transaction is 20%.

30. The price of a jewel, passing through three hands, rises on the whole by 65%. If the first and the second sellers make a profit of 20% and 25% respectively, find the percentage profit earned by the third seller.

15%

20%

25%

5%

When the jewel passes through the first seller, its price increases by 20%. Then, when it goes to the second seller, its price further increases by 25% from the price set by the first seller. By the time it reaches the third seller, the price has already risen by a total of 45% (20% from the first seller and 25% from the second seller). Since the overall price of the jewel increases by 65%, and 45% of this increase is already accounted for by the profits of the first two sellers, the remaining 20% increase must be the profit earned by the third seller. Therefore, the percentage profit earned by the third seller is 20%.
