1/10th of deer have electronic markers.
Also,percentage of tagged deer in the second sample approximates the percentage of tagged deer in the forest.
So, the answer is[spoiler] 150 x 10 = 1500 "D"[/spoiler]

It takes time and effort to explain, so if my comment helped you please press Thanks button

5 tagged corresponds to 50 deer
50 tagged to 50X50 deer

First sample : total 150 deers caught tagged
second sample: out of 50 only 5 were tagged. so 5 is 10% of 50

Now the stmt "percentage of tagged deer in the second sample approximates the percentage of tagged deer in the forest " means 10% of second sample is equvilaent to 150 deers of first sample.
so if 10% is 150, then 100%= 150*100= 15000

Now, I have one question to all the students regarding my profile name. I have adopted this name just for fun , but I would like to know whether adopting this name could land me in trouble in terms of trade marks/ copyrights etc , as this is a popular name of a fast food co. in India ? I just want to be on the safe side !
