- C.
  
  5
- D.
  
  6
Correct Answer
C. 5

Explanation
The given expression is solved using the order of operations, which states that multiplication and division should be done before addition and subtraction. First, we perform the multiplication and division from left to right: -3 x 2 = -6 and -6 : (-2) = 3. Then, we perform the addition and subtraction from left to right: -6 + 8 = 2 and 2 - 3 = -1. Therefore, the correct answer is -1, not 5.

- B.
  
  -5
- C.
  
  5
- D.
  
  10
Correct Answer
B. -5

Explanation
The given equation is 10 + (-2n) = 20. To solve for n, we need to isolate the variable. We can start by subtracting 10 from both sides of the equation, which gives us -2n = 10. Next, we divide both sides by -2 to solve for n. This gives us n = -5. Therefore, the value of n that satisfies the equation is -5.

Correct Answer
A. -8

Explanation
The correct answer is -8 because when we simplify the equation, we get 3x + 15 - 4 = 0. By combining like terms, we have 3x + 11 = 0. Then, we isolate the variable by subtracting 11 from both sides, resulting in 3x = -11. Finally, we divide both sides by 3 to solve for x, which gives us x = -11/3. Simplifying further, we get x = -8.

Febri mengunjungi perpustakaan 4 hari sekali. Jhoni mengunjungi perpustakaan 6 hari sekali. Pada tanggal 27 Agustus mereka mengunjungi perpustakaan bersama-sama. Mereka akan mengunjungi perpustakaan bersama-sama lagi untuk kedua kalinya pada tanggal . . .
- A.
  
  4 September
- B.
  
  8 September
- C.
  
  20 September
- D.
  
  21 September
Correct Answer
B. 8 September

Explanation
Febri visits the library every 4 days and Jhoni visits every 6 days. To find out when they will visit the library together again, we need to find the least common multiple (LCM) of 4 and 6. The LCM of 4 and 6 is 12. This means that they will visit the library together every 12 days. Since they visited the library together on August 27, the next time they will visit together will be 12 days later, which is September 8. Therefore, the answer is 8 September.

Jumlah umur ayah, ibu dan anaknya adalah 123 tahun. Umur ayah dua kali umur anaknya. Jika umur ibu 48 tahun, maka umur anak itu adalah . . .
- A.
  
  23 tahun
- B.
  
  24 tahun
- C.
  
  25 tahun
- D.
  
  26 tahun
Correct Answer
C. 25 tahun

Explanation
The total age of the father, mother, and child is 123 years. The father's age is twice the age of the child. Given that the mother is 48 years old, we can subtract her age from the total to find the combined age of the father and child, which is 123 - 48 = 75 years. Since the father's age is twice the age of the child, we can divide 75 by 3 (2 + 1) to find the age of the child, which is 25 years.

Apabila dari 30,5 meter kain yang tersedia, terjual bagian dan setengah dari sisanya dipakai sendiri, maka kain yang masih tersisa adalah . . .
- A.
  
  6,10 meter
- B.
  
  6,01 meter
- C.
  
  3,05 meter
- D.
  
  3,025 meter
Correct Answer
C. 3,05 meter

Explanation
Dalam soal ini, terdapat 30,5 meter kain yang tersedia. Kemudian, bagian dan setengah dari sisanya dipakai sendiri. Jadi, kita perlu menghitung berapa kain yang tersisa setelah bagian dan setengah sisanya digunakan. Bagian dan setengah dari sisanya adalah 30,5 meter - (30,5 meter/2) = 30,5 meter - 15,25 meter = 15,25 meter. Jadi, kain yang masih tersisa adalah 15,25 meter. Namun, dalam pilihan jawaban, terdapat angka 3,05 meter yang merupakan angka yang sama tetapi dalam bentuk desimal. Oleh karena itu, jawaban yang benar adalah 3,05 meter.

Hasil dari ( 3c - a )(3c + a) adalah . . .
- A.
- B.
- C.
- D.
Correct Answer
B.

Explanation
The expression (3c - a)(3c + a) can be simplified using the formula for the difference of squares, which states that (a - b)(a + b) = a^2 - b^2. In this case, we have (3c - a)(3c + a), so we can rewrite it as (3c)^2 - a^2. Simplifying further, we get 9c^2 - a^2. Therefore, the hasil (result) of the expression is 9c^2 - a^2.

Sebuah segitiga mempunyai alas ( 2x - 1 ) dan tinggi 6. Jika luas tidak lebih dari 39, maka nilai x adalah . . .
- A.
- B.
- C.
- D.
Correct Answer
C.

Explanation
To find the value of x, we can use the formula for the area of a triangle, which is 1/2 * base * height. In this case, the base is given as (2x - 1) and the height is given as 6. We can substitute these values into the formula to get the equation 1/2 * (2x - 1) * 6 = 39. Simplifying this equation, we get (2x - 1) * 6 = 78. Dividing both sides by 6, we get 2x - 1 = 13. Adding 1 to both sides, we get 2x = 14. Finally, dividing both sides by 2, we find that x = 7.

Correct Answer
B. -3 dan -2

Explanation
The correct answer is -3 and -2. This can be determined by looking at the pattern of the given numbers. The pattern is that the second number is always one less than the first number. Therefore, if the first number is -3, the second number would be -3 - 1 = -4. Similarly, if the first number is -2, the second number would be -2 - 1 = -3. Hence, the correct answer is -3 and -2.

- C.
  
  { ..., 0, 1, 2, 3 }
- D.
  
  { ..., 5, 6, 7, 8}
Correct Answer
C. { ..., 0, 1, 2, 3 }

Explanation
The correct answer is { ..., 0, 1, 2, 3 }. This is because the equation 2x + 5 = 11 can be solved by subtracting 5 from both sides to get 2x = 6, and then dividing both sides by 2 to get x = 3. Since x is a whole number, the set of solutions includes all integers greater than or equal to 3. Therefore, the set { ..., 0, 1, 2, 3 } represents the solution set for the equation.

Sebuah sepatu seharga Rp 180.000,- dijual dengan diskon 15%. Harga sepatu setelah didiskon adalah . . .
- A.
  
  Rp 175.000,-
- B.
  
  Rp 163.000,-
- C.
  
  Rp 153.000,-
- D.
  
  Rp 135.000,-
Correct Answer
C. Rp 153.000,-

Explanation
The original price of the shoes is Rp 180.000,-. The discount given is 15%, which means the customer will get 15% off the original price. To calculate the discounted price, we need to subtract 15% of Rp 180.000,- from the original price. 15% of Rp 180.000,- is Rp 27.000,-. Subtracting Rp 27.000,- from Rp 180.000,- gives us Rp 153.000,-, which is the final price of the shoes after the discount has been applied.

- C.
  
  Rugi Rp 28.000,-
- D.
  
  Untung Rp 28.000,-
Correct Answer
B. Untung Rp 18.000,-

Explanation
The pedagang bought three dozens of plates for Rp 198,000. Each dozen contains 12 plates, so the pedagang bought a total of 36 plates. If the pedagang sells each plate for Rp 6,000, the total revenue would be 36 plates multiplied by Rp 6,000, which is Rp 216,000. Since the revenue is higher than the cost of the plates, the pedagang will make a profit of Rp 18,000.

- B.
  
  6,4
- C.
  
  4,8
- D.
  
  4,6
Correct Answer
A. 8,4

Explanation
The correct answer is 8,4 because to find the number of minutes in 4% of 3.5 hours, we can first convert 3.5 hours to minutes by multiplying it by 60 (since there are 60 minutes in an hour). This gives us 210 minutes. Then, we can find 4% of 210 by multiplying 210 by 0.04. This gives us 8.4, which represents 4% of 3.5 hours in minutes.

  2%
- B.
  
  10%
- C.
  
  12%
- D.
  
  20%
Correct Answer
D. 20%

Explanation
The profit percentage can be calculated by finding the difference between the selling price and the cost price, dividing it by the cost price, and then multiplying by 100. In this case, the selling price of 4 dozens of pencils is 4 x 12 x 1,500 = Rp 72,000. The cost price of 4 dozens of pencils is 4 x 15,000 = Rp 60,000. The profit is Rp 72,000 - Rp 60,000 = Rp 12,000. The profit percentage is (12,000/60,000) x 100 = 20%. Therefore, the correct answer is 20%.

  Rp 7.200.000,-
- C.
  
  Rp 6.700.000,-
- D.
  
  Rp 7.600.000,-
Correct Answer
A. Rp 6.720.000,-

Explanation
The correct answer is Rp 6.720.000,- because the investment is compounded annually at a rate of 5%. After 5 years, the amount of money would have grown by 5% each year. To find the initial amount, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times that interest is compounded per year, and t is the number of years. Rearranging the formula, we can solve for P: P = A / (1 + r/n)^(nt). Plugging in the given values, we get P = 8,400,000 / (1 + 0.05/1)^(1*5) = 6,720,000.

- B.
  
  28 orang
- C.
  
  32 orang
- D.

Correct Answer
A. 18 orang

Explanation
The given question states that a contractor estimates that a job can be completed in 48 days with 14 workers. However, the question asks how many additional workers the contractor needs to hire in order to complete the job in 21 days. Since the number of workers is inversely proportional to the number of days required to complete the job, the contractor needs to hire more workers to reduce the number of days. By using the formula for inverse variation, we can calculate that the contractor needs to hire 18 additional workers to complete the job in 21 days.

B. 10

Explanation
The question states that two numbers have a ratio of 3:5. When each number is subtracted by 10, the ratio becomes 5:7. To find the difference between the largest and smallest numbers, we can set up a proportion using the given ratios. Let the original numbers be 3x and 5x. After subtracting 10, the numbers become (3x-10) and (5x-10). We can set up the proportion (3x-10)/(5x-10) = 5/7. Solving this proportion, we find x = 8. Therefore, the difference between the largest and smallest numbers is (5x-10) - (3x-10) = 10.
