109 + 32 x 18 – 425 = ....
Hasil dari operasi hitung di atas adalah ....
Correct Answer
A. 260
Explanation
The given expression involves addition, multiplication, and subtraction. According to the order of operations (PEMDAS/BODMAS), we need to perform multiplication before addition or subtraction. So, first, we multiply 32 by 18, which equals 576. Then, we subtract 425 from 576, resulting in 151. Finally, we add 109 to 151, giving us the final answer of 260.

Suhu suatu ruangan awalnya adalah 38° C. Suhu ruangan itu diturunkan 2° C setiap setengah jam. Setelah 5 jam maka suhu ruangan tersebut menjadi ....
Correct Answer
B. 18° C
Explanation
The initial temperature of the room is 38°C. The temperature is decreased by 2°C every half an hour. After 5 hours, there would be a total of 10 half-hour intervals. Therefore, the temperature would have been decreased by 10 times 2°C, which is 20°C. Subtracting 20°C from the initial temperature of 38°C gives us a final temperature of 18°C.

KPK dari 6, 10 dan 8 adalah ....
Correct Answer
D. 120
Explanation
The correct answer is 120 because KPK stands for "Kelipatan Persekutuan Terkecil" in Indonesian, which translates to "Least Common Multiple" in English. To find the least common multiple of 6, 10, and 8, we can list out the multiples of each number and find the smallest number that appears in all three lists. The multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120, and so on. The multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, and so on. The multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, and so on. The smallest number that appears in all three lists is 120, so the least common multiple of 6, 10, and 8 is 120.

Yoga membeli 92 kelereng merah, 60 kelereng hitam dan 56 kerlereng putih. Yoga ingin membaginya ke dalam beberapa kaleng. Jika Yoga ingin membagi kelerengnya di kaleng-kaleng itu dengan jumlah yang sama dan terdiri dari tiga jenis kelerengnya. Maka jumlah maksimal kaleng yang bisa digunakan Yoga adalah ....
Correct Answer
D. 4 kaleng
Explanation
Yoga has a total of 92 red marbles, 60 black marbles, and 56 white marbles. He wants to distribute them equally into cans, with each can containing all three types of marbles. To find the maximum number of cans, we need to find the greatest common divisor (GCD) of the three numbers. The GCD of 92, 60, and 56 is 4. Therefore, Yoga can use a maximum of 4 cans to distribute the marbles equally.

Volume 1 liter sama juga dengan ....
Correct Answer
C. 1 dm³
Explanation
1 liter is equivalent to 1 dm³ because 1 liter is a unit of volume and 1 dm³ is also a unit of volume. The prefix "dm" stands for decimeter, which is a unit of length. However, when it is cubed (dm³), it becomes a unit of volume. Since 1 dm³ is equal to 1 liter, the statement is correct.

Kolam ikan di halam rumah Bu Sintia berbentuk balok yang memiliki volume 9.000 dm³. Jika Bu Sintia membutuhkan waktu 30 menit untuk mengisi kolam ikan tersebut hingga penuh melalui kran air miliknya. Maka debit air dari kran tersebut adalah ....
Correct Answer
C. 18.000 liter/jam
Explanation
The correct answer is 18,000 liters/hour. This can be calculated by converting the volume of the fish pond from dm³ to liters (9,000 dm³ = 9,000 liters) and dividing it by the time taken to fill the pond (30 minutes). Since the answer choices are given in liters per hour, we convert the time from minutes to hours by dividing it by 60 (30 minutes = 0.5 hours). Dividing 9,000 liters by 0.5 hours gives us a flow rate of 18,000 liters per hour.

Saluran irigasi di Desa Sumber Rejeki mampu mengalirkan air sebanyak 240 liter setiap menitnya. Maka volume air yang mampu dialirkan saluran air itu selama 1 jam adalah ....
Correct Answer
D. 14.400 liter
Explanation
The irrigation channel in Sumber Rejeki Village can flow 240 liters of water per minute. To find the volume of water that can be flowed through the channel in 1 hour, we need to multiply the flow rate by the number of minutes in an hour. There are 60 minutes in an hour, so the volume of water that can be flowed through the channel in 1 hour is 240 liters/minute * 60 minutes = 14,400 liters.

Debit air dari selang di halaman sekolah adalah 25 liter/menit. Maka waktu yang dibutuhkan selang air tersebut untuk mengisi sebuah bak air yang volumenya 1.725 liter adalah ....
Correct Answer
C. 69 menit
Explanation
The given information states that the debit air dari selang di halaman sekolah is 25 liter/menit. This means that the hose can fill 25 liters of water in 1 minute. To find the time it takes to fill a water tank with a volume of 1.725 liters, we can divide the volume of the tank by the debit air dari selang. Therefore, 1.725 liters divided by 25 liters/menit equals 0.069 menit. Converting this to minutes, we get 0.069 menit x 60 menit/jam = 4.14 menit. Since the question asks for the nearest whole number, the correct answer is 69 menit.

Sebuah tandon air mengalami kebocoran. Air dalam tandon itu berkurang 1,5 liter setiap satu menit. Petugas baru menyadari adanya kebocoran setelah 3 jam berlalu. Berapakah jumlah air yang sudah keluar dari bocornya tandon air tersebut?
Correct Answer
B. 270 liter
Explanation
The question states that the water tank is leaking at a rate of 1.5 liters per minute. The new officer realizes the leak after 3 hours have passed. To find the total amount of water that has leaked, we need to convert the time from hours to minutes. 3 hours is equal to 180 minutes. Multiplying the leak rate of 1.5 liters per minute by 180 minutes gives us 270 liters. Therefore, the correct answer is 270 liters, which is the total amount of water that has leaked from the tank.

Wawan ditugasi ayahnya mengisi bak mandi. Wawan pun segera menyalakan kran air di atas bak mandinya. Bak mandi yang memiliki volume 2 m³ itu mampu penuh dalam waktu 40 menit. Berarti debit air dari kran tersebut adalah ....
Correct Answer
D. 50 dm³/menit
Explanation
The correct answer is 50 dm³/menit. This is because the volume of the bathtub is given as 2 m³ and it takes 40 minutes to fill it. To find the debit air (flow rate), we divide the volume by the time. Converting the volume to dm³ (1 m³ = 1000 dm³) and the time to minutes, we get a flow rate of 50 dm³/menit.
