Competition Road to the Olympia Summit 2020 has officially ended with a deserved victory for the only contestant: Nguyen Thi Thu Hang from Kim Son A High School (Ninh Binh).
When entering the final, the questions must be carefully selected and evaluated extremely difficult when the candidates are required to have a wide coverage of fields of Mathematics, Physics, Chemistry, Biology. .. to your knowledge of astronomy, science and experimentation in life.
In the end Road to the Olympia Summit 2020In the section on student Tuan Kiet’s finish line, a math question seemed to make things difficult for all four candidates:
“Let the letters O, L, Y, M denote different digits and the sum of OLYM, LOMY, YMOL, MYLO equal 29997. What is the sum of O + L + Y + M? “.
The math quiz makes it difficult for all 4 climbers. (Screenshots)
Unsurprisingly, the final 30-point question in the Finish contest has challenged all four “climbers.” Student Tuan Kiet then changed his answer 3 times as “20 – 10 – 15“But still wrong. After that, Quoc Anh rang the correct bell to answer with the answer”twenty“But MC Ngoc Huy has yet to announce regret and say the correct result 27.
In fact, this is a mathematical question that is not difficult, with the rule of quick mental arithmetic, but under the heat of the program with only 15 seconds, it is difficult for all 4 candidates.
The solution in this article is as follows:
OLYM = 1000 x O + 100 x L + 10 x Y + M
LOMY = 1000 x L + 100 x O + 10 x M + Y
YMOL = 1000 x Y + 100 x M + 10 x O + L
MYLO = 1000 x M + 100 x Y + 10 x L + O
Inferred: OLYM + LOMY + YMOL + MYLO = 1111 x (O + L + Y + M) = 29997
=> Total O + L + Y + M = 29997: 1111 = 27.
Below the video, many netizens left comments on this math question:
“I took it again to fix it but it took me 10 minutes to come out. All 4 up there under pressure, just 15 seconds is too hard“commented QT.
“The solution is not too difficult, but the study jacket, plus the exam mentality, no one can answer it., you share LN.
“This form has never been fulfilled before, it is not understood with the amount of time the program gives it. But having fulfilled it, 4 digits O, L, M, Y appear all in the 4 rows in 4 digits. Recognize the rule of the computer press is out“TN shared.
