After cleaning the rice, the weight of the rice decreased by 4kg. Therefore, the initial weight of the rice was 100kg + 4kg = 104kg. Since the question asks for the weight of the clean rice, we subtract the weight of the impurities from the initial weight: 104kg - 8kg = 96kg.

Dinda membeli baju dengan harga awal Rp 90.000,-. Kemudian, ada potongan harga 50%. Untuk menghitung harga setelah potongan, kita dapat mengalikan harga awal dengan persentase potongan (50% = 0.5). Jadi, harga setelah potongan adalah 90.000 x 0.5 = Rp 45.000,-.

Pajak adalah suatu kewajiban yang dibebankan kepada masyarakat untuk menyerahkan sebagian kekayaan kepada negara sesuai dengan peraturan-peraturan yang telah ditetapkan oleh pemerintah.

Nina bought 4kg of apples for Rp 40,000. She sells them at a loss of Rp 4,000 per kg. To find the total loss, we multiply the loss per kg by the total weight. Rp 4,000 x 4kg = Rp 16,000. Therefore, the total loss for Nina is Rp 16,000.

Bela membeli baju dengan harga Rp 85.000,- dan mendapatkan diskon sebesar 20%. Untuk menghitung uang yang harus dibayar oleh Bela, kita dapat mengurangi diskon dari harga awal. Diskon sebesar 20% dari Rp 85.000,- adalah (20/100) x Rp 85.000,- = Rp 17.000,-. Jadi, uang yang harus dibayar oleh Bela adalah Rp 85.000,- - Rp 17.000,- = Rp 68.000,-.

The correct answer is 32. The question states that Ani bought a snack that weighs 30 grams and the packaging weighs 2 grams. To find the total weight, we add the weight of the snack and the weight of the packaging together: 30 grams + 2 grams = 32 grams. Therefore, the total weight of the snack is 32 grams.

The loss incurred can be calculated by subtracting the selling price from the buying price. In this case, the buying price is Rp 2,400,000 and the selling price is Rp 1,935,000. By subtracting the selling price from the buying price, we get Rp 465,000. Therefore, the loss incurred is Rp 465,000.

The pedagang bought 40 kg of oranges at Rp 6,500 per kg. To find the total price, we multiply the weight (40 kg) by the price per kg (Rp 6,500), which equals Rp 260,000. Therefore, the correct answer is Rp 260,000.

The net weight of each can of milk is 1 kg. The total weight of all 5 cans is 6 kg. To find the gross weight of each can, we need to divide the total weight by the number of cans. Therefore, 6 kg divided by 5 cans equals 1.2 kg.

The profit can be calculated by subtracting the purchase price from the selling price. In this case, the purchase price is Rp 2.600.000 and the selling price is Rp 3.300.000. By subtracting the purchase price from the selling price, we get Rp 700.000, which represents the profit made from the transaction.

The total price of the durians can be calculated by subtracting the amount of change received from the total amount paid. In this case, the change received is Rp 30,000 and the total amount paid is the sum of 3 x Rp 100,000 = Rp 300,000. Therefore, the total price of the durians is Rp 300,000 - Rp 30,000 = Rp 270,000.

The correct answer is 40%. To find the percentage discount, we need to calculate the difference between the original price and the discounted price, and then divide it by the original price. In this case, the difference is Rp120,000 - Rp72,000 = Rp48,000. Dividing this by the original price (Rp120,000) gives us 0.4, which is equal to 40%. Therefore, the shoes are discounted by 40%.

The mother bought 5kg of oranges for Rp 30,000 and sold them with a profit of Rp 3,000 per kg. Therefore, the total profit she made is Rp 3,000 * 5kg = Rp 15,000. Adding this profit to the initial amount she spent, the mother now has Rp 30,000 + Rp 15,000 = Rp 45,000.

The total weight of the mangoes sold at Rp 7.000,- per kg is 30 kg, so the total revenue from selling these mangoes is 30 kg * Rp 7.000,-/kg = Rp 210.000,-. The remaining mangoes weigh 40 kg - 30 kg = 10 kg, and they are sold at Rp 6.000,- per kg, so the total revenue from selling these mangoes is 10 kg * Rp 6.000,-/kg = Rp 60.000,-. Therefore, the total sales revenue is Rp 210.000,- + Rp 60.000,- = Rp 270.000,-.

The trader bought 1 quintal (100 kg) of rice for Rp 6,000 per kg, which means he spent a total of Rp 600,000. He then sold the rice for Rp 620,000, making a profit of Rp 20,000. To calculate the percentage profit, we divide the profit by the cost price and multiply by 100. In this case, (20,000 / 600,000) x 100 = 3.33%. Therefore, the trader made a profit of 3.33%.

The correct answer is Rp 200.000,-. To determine the cost price of the item, we need to find the original price before the 5% profit was added. Since the profit is 5% of the cost price, we can use the formula: cost price + (5% of cost price) = selling price. Let's assume the cost price is x. So, x + (5% of x) = Rp 210.000,-. Simplifying the equation, we get 1.05x = Rp 210.000,-. Dividing both sides by 1.05, we find x = Rp 200.000,-, which is the cost price of the item.

The correct answer is "bunga tabungan". This is because the question states that Ana's money increases by 1% after 1 month of saving it in the bank. This increase in money is commonly referred to as "bunga tabungan" or "interest on savings".

The correct answer is Rp 180.000,- because the interest is calculated using simple interest formula, which is Principal x Rate x Time. In this case, the principal is Rp 2.000.000,-, the rate is 18% (or 0.18 in decimal form), and the time is 6 months. Plugging in these values into the formula, we get 2.000.000 x 0.18 x (6/12) = Rp 180.000,-. Therefore, the interest at the end of the sixth month is Rp 180.000,-.

After 1 year, the amount of money in the bank would be Rp 3,000,000 + (Rp 3,000,000 * 20%) = Rp 3,600,000. After another year, the interest would be calculated based on this new amount, resulting in Rp 3,600,000 + (Rp 3,600,000 * 20%) = Rp 4,320,000. However, since the question states that the interest is simple interest, the interest for the second year would be calculated based on the initial amount of Rp 3,000,000, resulting in Rp 3,000,000 + (Rp 3,000,000 * 20%) = Rp 3,600,000. Therefore, the total amount of money after 2 years would be Rp 3,000,000 + Rp 3,600,000 = Rp 4,200,000.

The correct answer is Rp 200.000,- because the question states that the merchant sells the item for Rp 210.000,- and makes a profit of 5% from the purchase price. To find the purchase price, we can divide the selling price by 1 plus the profit percentage (1 + 0.05). So, 210.000 / 1.05 = Rp 200.000,-.
