A zoo has 60 adult tigers and 30 cubs. The ideal adult : cub ratio for healthy breeding is 1 : 0.6. How many adult tigers must be removed to achieve this ratio?
Answer
Remove 10 adult tigers
The correct answer is Remove 10 adult tigers — 60 – 50 = 10 adults need to be removed.
Step-by-step solution
- Calculate the required number of adults for 30 cubs using ratio: adults = cubs / 0.6 = 30 / 0.6 = 50.
- Determine difference between current adults (60) and required (50).
- 60 – 50 = 10 adults need to be removed.
Common mistake: Adding rather than removing adults
Concept tested: Ratio adjustment in captive breeding
