Answer:
Percentage of cats = 33.33%
Explanation:
Given information,
→ 10 dogs
→ 13 cats
→ 4 rabbits
→ 8 birds
→ 4 horses
The total number of animals is,
→ 10 + 13 + 4 + 8 + 4
→ 39 animals
Now the percentage of cats is,
→ (Cats/Total animals) × 100
→ (13/39) × 100
→ (1/3) × 100
→ 100/3
→ 33.33%
Hence, the answer is 33.33%.
