A. A. Rp1.650.000,00
Explanation
The trader invested Rp1.500.000,00 and earned a profit of 10%. To calculate the total income, we need to add the profit to the initial investment. 10% of Rp1.500.000,00 is Rp150.000,00. Adding this profit to the initial investment, the total income for the day is Rp1.650.000,00.

### Pak Dedi membeli suatu sepeda motor bekas dengan harga Rp5.000.000 ,00. Dalam waktu satu minggu motor tersebut dijual kembali dengan harga 110% dari harga belinya. Tentukan keuntungan Pak Dedi.

• A.

A. Rp500.000,00

• B.

B. Rp1.000.000,00

• C.

C. Rp4.500.000,00

• D.

D. Rp5.500.000,00

A. A. Rp500.000,00
Explanation
Pak Dedi bought a used motorcycle for Rp5,000,000. Within one week, he sold the motorcycle for 110% of the purchase price. To find the profit, we need to calculate 110% of Rp5,000,000. 110% of Rp5,000,000 is Rp5,500,000. However, this is the selling price, not the profit. To find the profit, we need to subtract the purchase price from the selling price. Rp5,500,000 - Rp5,000,000 = Rp500,000. Therefore, the profit made by Pak Dedi is Rp500,000.

• D.

C. C. Rp50.000,00
Explanation
Pak Candra bought a used bicycle for Rp500,000.00. He then sold the bike again after one week for 110% of the purchase price. To calculate the profit, we need to find 110% of Rp500,000.00. 110% of Rp500,000.00 is Rp550,000.00. The profit made by Pak Candra is the difference between the selling price and the purchase price, which is Rp550,000.00 - Rp500,000.00 = Rp50,000.00. Therefore, the correct answer is c. Rp50,000.00.

### Pak Edi membeli mobil dengan harga Rp160.000.000,00. Setelah 6 bulan dipakai, Pak Edi menjual mobil tersebut dengan harga Rp140.800.000,00. Tentukan taksiran terdekat persentase kerugian yang ditanggung oleh Pak Edi.

• A.

A. 20%

• B.

B. 18%

• C.

C. 15%

• D.

D. 12%

D. D. 12%
Explanation
Pak Edi bought a car for Rp160,000,000. After 6 months of use, he sold the car for Rp140,800,000. To determine the closest estimate of the percentage of loss incurred by Pak Edi, we can calculate the percentage difference between the buying price and selling price. The difference is Rp160,000,000 - Rp140,800,000 = Rp19,200,000. To find the percentage, we divide this difference by the buying price and multiply by 100: (Rp19,200,000 / Rp160,000,000) x 100 = 12%. Therefore, the closest estimate of the percentage loss is 12%.

C. Rp46.400.000,00

• D.

D. Rp56.000.000,00

C. C. Rp46.400.000,00
Explanation
Pak Fandi bought a piece of land for Rp40,000,000. After 1 year, Pak Dedi sold the land with a profit of approximately 16%. To find the estimated selling price of the land owned by Pak Fandi, we need to add the profit to the original price. 16% of Rp40,000,000 is Rp6,400,000. Adding this profit to the original price gives us Rp46,400,000, which is the closest estimated selling price of the land.

### Seorang pedagang bakso mengeluarkan modal sebesar Rp1.000.000,00 untuk menjalankan usahanya. Dia mematok harga baksonya adalah Rp11.000 ,00 perporsi. Jika ia merencakan ingin mendapatkan keuntungan minimal Rp200.000,00 dari usaha baksonya tersebut, maka berapa porsi minimal yang harusnya dibuat?

• A.

A. 100 porsi

• B.

B. 109 porsi

• C.

C. 110 porsi

• D.

D. 120 porsi

C. C. 110 porsi
Explanation
The profit per portion of bakso is calculated by subtracting the cost per portion from the selling price per portion. In this case, the profit per portion would be Rp11,000 - Rp1,000 = Rp10,000. To achieve a minimum profit of Rp200,000, the number of portions needed would be Rp200,000 / Rp10,000 = 20 portions. Therefore, the minimum number of portions that should be made is 20 portions. Adding this to the initial investment of 100 portions, the total minimum number of portions that should be made is 100 + 20 = 120 portions. Therefore, the correct answer is d. 120 portions.

### Seorang penjual bakso mengeluarkan modal sebesar Rp1.000.000,00 untuk menjalankan usahanya. Dia mematok harga baksonya adalah Rp9.000,00 perporsi.Jika pada hari itu ia menanggung kerugian sebesar sekitar 5%, maka taksirlah berapa porsi yang terjual pada hari itu.

• A.

• B.

B. 86

• C.

C. 96

• D.

D. 106

D. D. 106
Explanation
The seller's total loss is 5% of the initial capital, which is 0.05 x Rp1.000.000,00 = Rp50.000,00. To cover this loss, the seller needs to sell Rp50.000,00 / Rp9.000,00 = 5.56 portions. Since the seller cannot sell a fraction of a portion, the seller needs to sell at least 6 portions to cover the loss. Therefore, the estimated number of portions sold on that day is 106.
