Luna's heart was pounding so hard that even her hands felt cold. He breathed and began to control himself. He was really nervous because his opponent was Lucia the smartest person in his class and also the person who hated him the most. Luna is as much as possible acting.
The semi-final round began, Luna was so nervous. He looked at Ali and Dilah, then he turned his gaze toward his supporters. His heart tried to strengthen itself.
I can't beat Mr. Ali and my backers. Luna
The host pointed to the LED screen, there are questions that will be answered.

Luna, Lucia, Rudi, and Ciko looked for answers by writing on the opaque paper. Not long after Lucia rang the bell. It made Luna, Rudi, and Ciko surprised.
"100 grams" said Lucia smiling cunningly.
"Right, 10 points for Lucia" the host said.
"The next question, Firman invested RP20,000,000.00 with compound interest of 5%/year. Then the great flower of the Word after 2 years is.."
The participants quickly fought to find answers.
The teeeet!
Lucia rang the bell making Luna, Riko, and
Ciko frustrates. The head of the International School was astonished.
"Rp22,050,000" Lucia replied with a faint smile.
"Right, 10 points for Lucia. Let's give her a round of applause" said the host to encourage Lucia.
"The next question, a box contains 5 red balls, 4 blue balls and 3 yellow balls. From inside the box are taken 3 balls at once randomly. The odds of 2 red balls and 1 blue ball are..."
The participants re-write on the opaque paper in search of answers.
Teeeet!
"2/11 chances to take 2 red balls and 1 blue ball," said Luna confident.
"Damn!" annoyed Lucia because she lost quickly squeezed the bell.
"Right, 10 points for Luna,"
"Next problem, f(x)\=(x¹+1)¹ and f¹(a)\=320a with a>0 then a²-a²\=...."
Teeeet
Luna rang the bell, "0" she replied confidently.
Rudi rubbed his annoyed face, he had not even answered at all whereas Ciko was just scratching his head, he was confused how to defeat the two beautiful girls.

"It's really hard,"

Ciko rang the bell, leaving the principal of the International School High School flabbergasted. Because their representative Rudi has not answered at all about the given yamg. Though Rudi is a representative of SMA International School.
"E" said Ciko without hesitation.
"Right, 10 points for Ciko." most of the audience applauded Ciko.
"Lucia's temporary record is 20 points, Luna's 20 points, Ciko's 10 points, and Rudi's still 0,"
"Heh, what kind of flagship representative is this? You know it's not that International School High School has always won for the last 25 years, Mulya. If Rudi doesn't win this race, I'll fire you!" the headmaster of the International School High School glared sharply at his mentor teacher.
