The Road to Olympia puzzle 'knocks out' 99% of players

This calculation question is not really difficult, but with the requirement of finding the answer within 15 seconds, it is already making the student lose his mind.

In the Finish Line competition, the organizers of the Road to Olympia asked the following question: "Bird A was flying when he met a flock of birds B flying in the opposite direction, so he said: "Hello, my friend." The leader bird replied: "Hello, we are not 100, but all of us, plus all of us, plus half of us, then plus a quarter of us and you, to make 100." How many birds are there in flock B?"

This puzzle will stump 99% of those who face it.

This question is worth 30 points, contestant Bao Phu could not give the correct answer. Due to time pressure, the other 3 contestants could not give the correct answer either.
