1. Seorang pedagang membeli 5 ekor ayam dengan harga Rp. 250.000,00. Kemudian ayam tersebut dijual kembali dengan harga Rp. 60.000,00 perekornya. Jika ayam tersebut habis terjual maka keuntungan pedagang tersebut adalah…

Rp. 10.000,00

Rp. 30.000,00

Rp. 40.000,00

Rp. 50.000,00

The profit of the merchant can be calculated by subtracting the cost price from the selling price. The cost price of 5 chickens is Rp. 250,000.00, so the cost price per chicken is Rp. 250,000.00 / 5 = Rp. 50,000.00. The selling price per chicken is Rp. 60,000.00. Therefore, the profit per chicken is Rp. 60,000.00 - Rp. 50,000.00 = Rp. 10,000.00. Since the merchant sold all the chickens, the total profit is Rp. 10,000.00 x 5 = Rp. 50,000.00.

Explanation

The profit of the merchant can be calculated by subtracting the cost price from the selling price. The cost price of 5 chickens is Rp. 250,000.00, so the cost price per chicken is Rp. 250,000.00 / 5 = Rp. 50,000.00. The selling price per chicken is Rp. 60,000.00. Therefore, the profit per chicken is Rp. 60,000.00 - Rp. 50,000.00 = Rp. 10,000.00. Since the merchant sold all the chickens, the total profit is Rp. 10,000.00 x 5 = Rp. 50,000.00.

2. Paman membeli 2 lusin buku tulis dengan harga Rp. 24.000,00. Buku tersebut dijual kembali dengan memperoleh keuntungan 20%. Maka harga jual setiap bukunya adalah….

Rp. 1.000,00

Rp. 1.200,00

Rp. 1.500,00

Rp. 2.000,00

The correct answer is Rp. 1.200,00. To find the selling price of each book, we need to calculate the cost price of each book first. Paman bought 2 dozen (24) books for Rp. 24,000. So, the cost price of each book is Rp. 24,000 divided by 24, which is Rp. 1,000. To calculate the selling price, we need to add a 20% profit to the cost price. 20% of Rp. 1,000 is Rp. 200. Adding this profit to the cost price gives us Rp. 1,000 + Rp. 200 = Rp. 1,200. Therefore, the selling price of each book is Rp. 1,200.

Rp. 200.000,00

Rp. 240.000,00

Rp. 250.000,00

Rp. 260.000,00

Wati membeli sepasang sepatu dengan harga Rp. 300.000,00 dan mendapat diskon sebesar 20%. Diskon sebesar 20% dari harga Rp. 300.000,00 adalah (20/100) x Rp. 300.000,00 = Rp. 60.000,00. Jadi, Wati harus membayar sepatu tersebut sebesar Rp. 300.000,00 - Rp. 60.000,00 = Rp. 240.000,00.

Rp. 220.000,00

Rp. 250.000,00

Rp. 253.000,00

Rp. 270.000,00

Iwan membeli jam tangan dengan harga Rp. 275.000,00 dan mendapat diskon sebesar 8%. Untuk menghitung harga yang harus dibayar, kita dapat mengalikan harga awal dengan persentase diskon yang diberikan, yaitu 8%. 8% dari Rp. 275.000,00 adalah Rp. 22.000,00. Jadi, harga yang harus dibayar oleh Iwan adalah Rp. 275.000,00 - Rp. 22.000,00 = Rp. 253.000,00.

Rp. 15.800.000,00

Rp. 15.750.000,00

Rp. 14.250.000,00

Pak Wayan harus membayar sebesar Rp. 15.750.000,00. Hal ini dapat dihitung dengan mengalikan harga sepeda motor (Rp. 15.000.000,00) dengan persentase pajak penjualan (5%) kemudian menambahkannya ke harga sepeda motor. Jadi, Rp. 15.000.000,00 x 5% = Rp. 750.000,00. Kemudian, Rp. 15.000.000,00 + Rp. 750.000,00 = Rp. 15.750.000,00.

10. Ibu membeli 5 rak telur dengan harga Rp. 27.000,00 setiap raknya. Setiap rak berisi 30 butir telur. Jika ibu ingin memperoleh untung sebesar Rp. 500,00 perbutirnya. Maka harga jual seluruhnya adalah….

Rp. 210.000,00

Rp. 220.000,00

Rp. 250.000,00

Rp. 300.000,00

The total cost of 5 racks of eggs is 5 x Rp. 27,000 = Rp. 135,000. Each rack contains 30 eggs, so there are a total of 5 x 30 = 150 eggs. If the mother wants to make a profit of Rp. 500 per egg, the total profit would be 150 x Rp. 500 = Rp. 75,000. The selling price would then be the cost price plus the profit, which is Rp. 135,000 + Rp. 75,000 = Rp. 210,000. Therefore, the correct answer is Rp. 210,000.

Explanation

The total cost of 5 racks of eggs is 5 x Rp. 27,000 = Rp. 135,000. Each rack contains 30 eggs, so there are a total of 5 x 30 = 150 eggs. If the mother wants to make a profit of Rp. 500 per egg, the total profit would be 150 x Rp. 500 = Rp. 75,000. The selling price would then be the cost price plus the profit, which is Rp. 135,000 + Rp. 75,000 = Rp. 210,000. Therefore, the correct answer is Rp. 210,000.

11. Pak Robert membeli sekarung gula pasir dengan berat bruto 50 kg dan taranya 2%. Bila harga beli sekarung gula pasir Rp. 100.000,00 dan dijual lagi dengan harga Rp. 2.500,00 per kg. Keuntungan Pak Robert seluruhnya adalah….

Rp. 20.000,00

Rp. 22.000,00

Rp. 22.500,00

Rp. 23.500,00

Pak Robert membeli sekarung gula pasir dengan berat bruto 50 kg dan taranya 2%. Berat bersih sekarung gula pasir setelah dikurangi taranya adalah 50 kg - (2% x 50 kg) = 50 kg - 1 kg = 49 kg. Harga jual per kg adalah Rp. 2.500,00, sehingga harga jual seluruhnya adalah 49 kg x Rp. 2.500,00 = Rp. 122.500,00. Keuntungan Pak Robert adalah harga jual seluruhnya dikurangi harga beli, yaitu Rp. 122.500,00 - Rp. 100.000,00 = Rp. 22.500,00. Therefore, the correct answer is Rp. 22.500,00.

Keuntungan Pak Robert adalah harga jual seluruhnya dikurangi harga beli, yaitu Rp. 122.500,00 - Rp. 100.000,00 = Rp. 22.500,00. Therefore, the correct answer is Rp. 22.500,00.

12. Bu Aminah menjual cincin dengan harga Rp. 450.000,00. Ia mendapat kerugian sebesar 10%. Maka harga beli cincin tersebut adalah….

Rp. 460.000,00

Rp. 550.000,00

Rp. 525.000,00

Rp. 500.000,00

Aminah sold the ring for Rp. 450,000. Since she incurred a loss of 10%, the selling price represents 90% of the buying price. To find the buying price, we can set up the equation: 90% of the buying price = Rp. 450,000. Solving for the buying price, we can divide both sides of the equation by 90% (or multiply by 100/90), which gives us Rp. 500,000. Therefore, the buying price of the ring is Rp. 500,000.

13. Seorang pedagang membeli 20 lusin buku dengan harga Rp. 10.000,00 perlusinnya. Buku tersebut dijual kembali dengan harga Rp. 1.000,00 perbuku. Keuntungan pedagang tersebut adalah….

Rp. 20.000,00

Rp. 30.000,00

Rp. 40.000,00

Rp. 50.000,00

The trader bought 20 dozen books at a price of Rp. 10,000.00 per dozen. This means that the total cost of buying the books is 20 x Rp. 10,000.00 = Rp. 200,000.00. The books are then sold at a price of Rp. 1,000.00 per book. Since there are 20 dozen books, which is equal to 20 x 12 = 240 books, the total selling price is 240 x Rp. 1,000.00 = Rp. 240,000.00. The profit made by the trader is the difference between the selling price and the cost price, which is Rp. 240,000.00 - Rp. 200,000.00 = Rp. 40,000.00. Therefore, the correct answer is Rp. 40,000.00.

The books are then sold at a price of Rp. 1,000.00 per book. Since there are 20 dozen books, which is equal to 20 x 12 = 240 books, the total selling price is 240 x Rp. 1,000.00 = Rp. 240,000.00. The profit made by the trader is the difference between the selling price and the cost price, which is Rp. 240,000.00 - Rp. 200,000.00 = Rp. 40,000.00. Therefore, the correct answer is Rp. 40,000.00.

14. Seorang pedagang membeli 20 lusin piring dengan harga Rp. 24.000,00 perlusinnya. Piring tersebut dijual lagi dengan harga Rp. 2.500,00 perbuahnya. Keuntungan pedagang tersebut adalah….

20%

25%

10%

15%

The profit percentage for the merchant 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 cost price of one dozen plates is Rp. 24,000. The selling price of one plate is Rp. 2,500. To find the profit percentage, we can use the formula: (Selling Price - Cost Price) / Cost Price * 100. Plugging in the values, we get: (2,500 - 2,000) / 2,000 * 100 = 25%. Therefore, the correct answer is 25%.

Rp. 515.000,00

Rp. 510.000,00

Wulan menabung di bank sebesar Rp. 500.000,00 dengan bunga 6% pertahun. Setelah 6 bulan, Wulan akan mendapatkan bunga sebesar 6% x Rp. 500.000,00 = Rp. 30.000,00. Jadi, jumlah uang Wulan setelah 6 bulan adalah Rp. 500.000,00 + Rp. 30.000,00 = Rp. 530.000,00. However, none of the given options match this amount. Therefore, the correct answer is not available.

Rp. 180.000,00

Rp. 190.000,00

Rp. 200.000,00

Rp. 210.000,00

Rudi sold the bicycle for Rp. 240,000.00 and made a 20% profit. To find the cost price of the bicycle, we need to subtract the profit from the selling price. 20% of Rp. 240,000.00 is Rp. 48,000.00. Subtracting this from the selling price gives us Rp. 192,000.00, which is the cost price of the bicycle. Therefore, the correct answer is Rp. 200,000.00, which is the closest option to the cost price.

Rp. 6.800.000,00

Rp. 7.000.000,00

Rp. 7.200.000,00

If Pak Ali sells a motorcycle for Rp. 5,600,000 and incurs a loss of 20%, it means that the selling price is only 80% of the original price. To find the original price, we can divide the selling price by 80% (0.8). So, 5,600,000 / 0.8 = Rp. 7,000,000. Therefore, the purchase price of the motorcycle is Rp. 7,000,000.
