Question
A kennel has 45 dogs in total, some are puppies, and some are adult dogs. The ratio of puppies to adult dogs in a kennel is 3:2. The number of puppies is ______.
- 27
- 18
- 35
- 20
Hint:
A ratio indicates how many times one number contains another.
The correct answer is: 27
Here, it is given that there are 45 dogs in a kennel and the ratio of adult dogs to puppies is 3:2. We have to find the number of puppies in the kennel.
Let the number of adult dogs and puppies be 3x and 2x.
Then, 3x + 2x = 45. [Total number of dogs]
=> 5x = 45.
=> x = 45/5 = 9.
So, number of puppies = 2x = 2 × 9 = 18.
Hence, the correct option is B.
Total number of dogs in the kennel = number of adult dogs + number of puppies.
