The image contains a set of math-related multiple-choice questions. I'll extract and solve the questions for you. Here's the detailed analysis and solution:

Question 1:

Untuk membuat satu loyang kue dan bolu, dibutuhkan 200 gram tepung terigu dan 250 gram telur. Rasio banyak tepung terhadap telur adalah ...

Options:

• A. 3 : 4
• B. 4 : 3
• C. 5 : 4
• D. 5 : 2

Solution: The ratio of tepung (200 grams) to telur (250 grams): $\text{Ratio} = \frac{200}{250} = \frac{4}{5}$ Answer: C. 4 : 5

Question 2:

Di dalam kelas terdapat 40 siswa, 24 siswa di antaranya adalah laki-laki. Rasio banyak siswa laki-laki dan siswa perempuan adalah ...

Options:

• A. 3 : 5
• B. 4 : 3
• C. 5 : 2
• D. 5 : 4

Solution: Total students = 40, Male = 24, Female = $40 - 24 = 16$. Ratio of males to females: $\text{Ratio} = \frac{24}{16} = \frac{3}{2}$ Answer: C. 3 : 2

Question 3:

Usia ayah adalah 3 tahun lebih tua dari usia ibu. Usia ibu dan anak pertamanya berbeda 22 tahun. Jika usia ibu saat ini adalah 27 tahun, rasio usia anak pertama dan ayah adalah ...

Options:

• A. 1 : 5
• B. 1 : 4
• C. 1 : 3
• D. 1 : 6

Solution:

• Age of mother = 27 years.
• Age of first child = $27 - 22 = 5$ years.
• Age of father = $27 + 3 = 30$ years.
• Ratio of child's age to father's age: $\text{Ratio} = \frac{5}{30} = \frac{1}{6}$ Answer: D. 1 : 6

Question 4:

Amira mempunyai koleksi buku cerita dan buku pengetahuan. Buku pengetahuan yang dimiliki 8 buku lebih banyak dari buku cerita. Jika total banyak buku adalah 64, maka banyak buku cerita adalah ...

Options:

• A. 28
• B. 32
• C. 36
• D. 40

Solution: Let the number of cerita books = $x$, and the number of knowledge books = $x + 8$. Total books = 64: $x + (x + 8) = 64$ $2x + 8 = 64 \implies 2x = 56 \implies x = 28$ Answer: A. 28
