Problema Solution
To determine the number of deer in a game preserve, a conservationist catches 506 deer, tags them and lets them loose. Later, 342 deer are caught; 171 of them are tagged. How many deer are in the preserve?
Answer provided by our tutors
The conservationist catches 506 deer
When 342 deer are caught later, 171 of them are tagged, which means 171 / 342 = 1/2 of all deer in the preserve are tagged
Since we know 506 deer were tagged, and 1/2 of all deer are tagged, then there are 506 / (1/2) = 1012 deer in the preserve
