Most percentage questions can be easily solved by assuming values, especially in case the answer is also a percentage.
If there are 100 birds, 20% are tagged so 20 are tagged.
Out of the rest 80, 30 should be tagged so that a total of 50% are tagged.
30/80 = 37.5%

Thanks, this is a clear explanation.
I noticed you often recommend the "weighted average" / alligation method.
Is it a case where we could have used it as well ?
When is it preferable to go percentage way vs alligation ?
