The correct answer is Rp. 1.500.000,-. The trader bought the ring for Rp. 1.250.000,- and made a profit of 20%. To calculate the selling price, we need to add the profit to the buying price. 20% of Rp. 1.250.000,- is Rp. 250.000,-. Adding this profit to the buying price gives us Rp. 1.250.000,- + Rp. 250.000,- = Rp. 1.500.000,-, which is the selling price of the ring.

The total income that the trader obtained can be calculated by adding the profit to the initial capital. Therefore, the income is Rp. 1,500,000 + Rp. 225,000 = Rp. 1,725,000.

Ayah membeli sepeda seharga Rp. 800.000,- dan mengalami kerugian sebesar 10%. Untuk mencari harga jual sepeda, kita perlu mengurangi 10% dari harga beli. 10% dari Rp. 800.000,- adalah Rp. 80.000,-. Jadi, harga jual sepeda adalah Rp. 800.000,- - Rp. 80.000,- = Rp. 720.000,-.

Pak Hari bought a goat for Rp. 2,000,000 and sold it for Rp. 2,240,000. To find the percentage profit, we can use the formula: (Profit/Cost Price) x 100. The profit made by Pak Hari is Rp. 2,240,000 - Rp. 2,000,000 = Rp. 240,000. Now we can calculate the percentage profit: (240,000/2,000,000) x 100 = 12%. Therefore, the correct answer is 12.

Pak Budi bought 3 boxes of fresh drinks for Rp. 240,000. Each box contains 40 glasses of drinks. If he sells each glass for Rp. 2,500, then the profit obtained is Rp. 60,000. This can be calculated by multiplying the number of glasses (3 boxes x 40 glasses) by the selling price per glass (Rp. 2,500), which equals Rp. 300,000. Then, subtract the cost of buying the drinks (Rp. 240,000) from the total sales (Rp. 300,000), resulting in a profit of Rp. 60,000.

The original price of the book can be calculated by dividing the discounted price by (100% - 10%). In this case, 100% - 10% = 90%. So, Rp. 54,000 is 90% of the original price. By dividing Rp. 54,000 by 90% or 0.9, we get Rp. 60,000 as the original price of the book before the discount.

The consumer bought the motorcycle for Rp. 16,000,000 and sold it for Rp. 15,000,000. To find the percentage loss, we need to calculate the difference between the buying price and the selling price, which is Rp. 16,000,000 - Rp. 15,000,000 = Rp. 1,000,000. Then, we divide this difference by the buying price and multiply it by 100 to get the percentage loss: (Rp. 1,000,000 / Rp. 16,000,000) * 100 = 6.25%. Therefore, the correct answer is 6.25%.

The correct answer is Rp. 2.975.000,- because the question states that the store gives a discount of 15%. To find the amount that needs to be paid by the mother, we need to subtract 15% of the original price from the original price. 15% of Rp. 3.500.000,- is Rp. 525.000,-. Subtracting this from the original price gives us Rp. 2.975.000,-.

The correct answer is Rp. 3.000.000,-. The question states that the gold merchant sells a bracelet for Rp. 3.150.000,- and makes a profit of 5%. To find the cost price of the bracelet, we can use the formula: Selling Price = Cost Price + Profit. Rearranging the formula, we get Cost Price = Selling Price - Profit. Therefore, the cost price of the bracelet is Rp. 3.150.000,- - 5% of Rp. 3.150.000,-, which equals Rp. 3.000.000,-.

To calculate the minimum number of jars the cake entrepreneur needs to sell to make a profit, we divide the total capital needed by the selling price of each jar. In this case, the total capital needed is Rp. 800,000 and the selling price per jar is Rp. 50,000. Therefore, the minimum number of jars that need to be sold is 800,000 / 50,000 = 16. However, since we are looking for the minimum number of jars to make a profit, we need to round up to the nearest whole number, which is 17.
