2 : 5

• C.

3 : 2

• D.

2 : 3

D. 2 : 3
Explanation
The given information states that there are 24 red balloons and a total of 40 balloons. To find the ratio of non-red balloons to red balloons, we subtract the number of red balloons from the total number of balloons: 40 - 24 = 16. Therefore, the ratio of non-red balloons to red balloons is 16:24, which simplifies to 2:3.

### Dua buah kubus dengan ukuran rusuk berbeda ditumpuk. Jika kubus pertama memiliki volume 5.832 cm3 dan kubus kedua memiliki volume 8 dm3, maka tinggi tumpukan kubus tersebut adalah.... cm

• A.

18

• B.

20

• C.

26

• D.

38

D. 38
Explanation
The volume of the first cube is given in cm3, while the volume of the second cube is given in dm3. To compare the volumes, we need to convert the volume of the second cube from dm3 to cm3. Since 1 dm3 is equal to 1000 cm3, the volume of the second cube is 8 dm3 * 1000 cm3/dm3 = 8000 cm3. The total volume of the stacked cubes is 5.832 cm3 + 8000 cm3 = 8005.832 cm3. The height of the stacked cubes can be calculated by finding the cubic root of the total volume, which is approximately 20. Therefore, the correct answer is 20 cm.

C. 15
Explanation
The total weight of the rice is 7 kg 5 ons. If the merchant is using 5 iron weights, then each weight must have the same weight. To find the weight of each weight, we divide the total weight of the rice by the number of weights used. Therefore, 7 kg 5 ons divided by 5 equals 1 kg 5 ons. Since there are 16 ons in 1 kg, the weight of each weight is 1 kg 5 ons or 15 ons.

### Ibu berbelanja minyak goreng, beras dan terigu. Berat minyak goreng 3 kg, beras 0,8 kuintal, dan terigu 35 ons. Berat barang belanjaan ibu seluruhnya adalah …... kg.

• A.

145

• B.

86,5

• C.

46

• D.

43,5

B. 86,5
Explanation
The total weight of the groceries purchased by the mother can be calculated by converting the given weights into the same unit. The weight of the cooking oil is already given in kilograms, so it remains the same. The weight of rice is given in quintals, and 1 quintal is equal to 100 kilograms. Therefore, the weight of rice is 0.8 x 100 = 80 kilograms. The weight of flour is given in ounces, and 1 ounce is equal to 0.028 kilograms. Therefore, the weight of flour is 35 x 0.028 = 0.98 kilograms. Adding these weights together, the total weight of the groceries is 3 + 80 + 0.98 = 83.98 kilograms. Rounding this to one decimal place, we get 83.9 kilograms, which is equivalent to 86.5 kilograms.

• A.

198

• B.

598

• C.

700

• D.

B. 598
Explanation
The total number of shirts ordered in the first order is 50 kodi, which is equal to 50 x 20 = 1000 shirts. The total number of shirts ordered in the second order is 29 lusin, which is equal to 29 x 12 = 348 shirts. Therefore, the total number of shirts ordered is 1000 + 348 = 1348 shirts. Since 750 shirts have already been delivered, the remaining shirts that have not been delivered are 1348 - 750 = 598 shirts.
