Solution
Given:
- •Ratio of Collies to Labs = 5:9
•There are 66 Golden Retrievers
•There are 12 more Golden Retrievers than Labs
To find:
- •The percent of dogs, which are Collies
Approach and Working:
As the ratio of Collies to Labs is 5:9, we can assume the number of Collies as 5x and number of Labs as 9x
- •Therefore, number of Golden Retrievers = 9x + 12
•Given that, 9x + 12 = 66
Or, 9x = 54
Or, x = 6
•Total dogs = 5x + 9x + 66 = 5*6 + 9*6 + 66 = 30 + 54 + 66 = 150
•Collies
