    Explanation
    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.

  • 6. 

    Ibu membeli beras 100kg, setelah beras dibersihkan dari kerikilnya berat beras berkurang 4kg. Berapa berat bersih beras?

    • A.

      91

    • B.

      93

    • C.

      94

    • D.

      96

    Correct Answer
    D. 96
    Explanation
    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.

    B. 32
    Explanation
    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.

    Dinda membeli baju seharga Rp 90.000,-, setelah mendapat potongan harga 50% berapa harga baju Dinda?

    • A.

      Rp 45.000,-

    • D.

      Rp 55.000,-

    Correct Answer
    A. Rp 45.000,-
    Explanation
    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,-.

    Rara membeli Sepatu seharga Rp120.000,-, setelah mendapat potongan harga sepatunya menjadi Rp 72.000,-. berapa % potongan harga sepatunya?

    • A.

      20%

    • B.

      30%

    • C.

      40%

    • D.

      50%

    Correct Answer
    C. 40%
    Explanation
    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%.

    • D.

      Rp 265.000,-

    Correct Answer
    C. Rp 260.000,-
    Explanation
    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.

    • A.

      Rp 200.000,-

    • B.

      Rp 250.000,-

    • C.

      Rp 255.000,-

    • D.

      Rp 260.000,-

    Correct Answer
    A. Rp 200.000,-
    Explanation
    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,-.

  • 12. 

    Seorang pedagang membeli mangga sebanyak 40kg, kemudian 30kg diantaranya dijual dengan harga Rp 7.000,- per kg, dan sisanya dijual dengan harga Rp 6.000,- per kg. Hitunglah harga penjualannya.

    • A.

      Rp 243.000,-

    • B.

      Rp 256.000,-

    • C.

      Rp 260.000,-

    • D.

      Rp 270.000,-

    Correct Answer
    D. Rp 270.000,-
    Explanation
    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,-.

    • B.

    • C.

      Rp 280.000,-

    • D.

      Rp 285.000,-

    Correct Answer
    A. Rp 270.000,-
    Explanation
    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.

    • B.

      2,33%

    • C.

      3,33%

    • D.

      4,33%

    Correct Answer
    C. 3,33%
    Explanation
    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%.

    Ani menjual suatu barang dengan harga Rp 210.000,- dan mendapat untung 5% dari harga beli. Tentukan harga beli barang tersebut.

    • A.

      Rp 180.000,-

    • B.

      Rp 185.000,-

    • C.

      Rp 195.000,-

    • D.

      Rp 200.000,-

    Correct Answer
    D. Rp 200.000,-
    Explanation
    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.

    • B.

      Rp 68.000,-

    • C.

      Rp 78.000,-

    • D.

      Rp 79.000,-

    Correct Answer
    B. Rp 68.000,-
    Explanation
    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,-.

    • C.

      1,6 kg

    • D.

      1,8 kg

    Correct Answer
    A. 1,2 kg
    Explanation
    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.

    • C.

      Rp 180.000,-

    • D.

      Rp 190.000,-

    Correct Answer
    C. Rp 180.000,-
    Explanation
    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,-.

    • C.

      Rp 4.200.000,-

    • D.

      Rp 4.400.000,-

    Correct Answer
    C. Rp 4.200.000,-
    Explanation
    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.
