9/10 people “give up”!
Road to the Top Olympia There are many interesting knowledge questions in the fields of Geography, History, Mathematics… However, many times the contest is also controversial when it comes to trivia questions but the thinking time is only 15-20 seconds, too much puzzle for candidates.
For example, in the contest last month, a math question appeared: “A square lawn surrounded by a fence, with an area of 100 square meters. In one corner of the lawn there is a tree stump and a cow is standing. A rope 5 meters long is tied to a tree. What is the maximum area of grass the cow can eat, knowing that the area of the tree is insignificant?”.
Olympia contestant calculated the result of 25m2 but the result was wrong.
After that, another contestant pressed the bell to win the right to answer with the answer 78.54m2, but still wrong.
Olympia question puzzles the contestants
The key to this math problem is the quizzes. Many people also miscalculated the other 78.54m2 result. When deducing that the maximum area the cow can eat is the area of a circle with a radius of 5 meters (the length of the rope).
However, reading the topic carefully, we see that the cow is NOT tied to a rope. That is, the cow will be able to walk freely all over the lawn. Therefore the maximum area of grass that the cow can eat = square lawn area = 100m2.
MC Khanh Vy also notes for candidates: “This is also a note to consider for the contestants of The Road to Olympia. It is to read the given topic carefully. Sometimes a small detail that you overlook can cost you your chance to win. point”.
This clever way of making questions always makes Olympia candidates easy to lose points, especially when limiting the time to only about 15-30 seconds for both thinking and answering.
Some comments on this Math puzzle:
– “Experience in competing in big competitions. If you want to do the right thing, read and understand all the questions. No one would put all the numbers in to just assemble the formula. A big contest like that is not easy to go wrong. So think about it a bit, the maximum area is 100m2, because the rope is tied to the stump, not the cow.A question with ‘approximate’ words like maximum or minimum will be very difficult. easy to puzzle”.
– “In a stressful exam, asking a trick like this is also a quiz for candidates, who can play again. Olympia is too scary”.
– “Do we each feel that this question is a bit too much, the candidate is stressed, who is in the mood to analyze whether it is a quiz or not?”
