In the Maths Olympiad of 2020 at Animal Planet, two representatives from the donkey’s side, while solving a quadratic equation, committed the following mistakes: (i) One of them made a mistake in the constant term and got the roots as 5 and 9. (ii) Another one committed an error in the coefficient of x and he got the roots as 12 and 4.But in the meantime, they realised that they are wrong and they managed to get it right jointly. Find the quadratic equation.
  • a)
    x2 + 4x + 14 = 0
  • b)
    2x2 + lx - 24 = 0
  • c)
    x2 - 14x + 48 = 0
  • d)
    3x2 - 17x + 52 = 0
Correct answer is option 'C'. Can you explain this answer?

STUDENT 1:

Roots: 5,9.

Hence, x= 5..or x=9

or, x-5 = 0 or x - 9 = 0

or, (x - 5)(x - 9) = 0

or, x2 - 14x + 45 = 0

STUDENT 2:

Roots: 12,4

Hence, x= 12..or x=4

or, x - 12 = 0 or x - 4 = 0

or, (x - 12)(x - 4) = 0

or, x2 - 14x + 48 = 0

Team and two representatives from the elephant team were selected to participate. The participants were asked to solve a series of challenging math problems.

The first problem was as follows:

Problem 1: Find the value of x if 3x + 5 = 17.

Both teams quickly started working on the problem. The donkey team representative, named Jack, immediately wrote down the equation and began solving it step by step.

Jack's Solution:
3x + 5 = 17
Subtract 5 from both sides:
3x = 12
Divide both sides by 3:
x = 4

While Jack was busy solving the problem, the elephant team representative, named Emily, was also working on the problem. She had a different approach to solving it.

Emily's Solution:
3x + 5 = 17
Subtract 5 from both sides:
3x = 12
Divide both sides by 3:
x = 4

Both Jack and Emily arrived at the same solution, x = 4. They were both excited and proud of their teamwork and problem-solving skills.

The participants moved on to the next problem, eager to put their math skills to the test once again.

Team and two representatives from the elephant team competed against each other. The donkey team representatives were named Alice and Bob, while the elephant team representatives were named Charlie and David.

The first round of the Olympiad was a multiple-choice test consisting of 20 questions. Each correct answer awarded 5 points, while each incorrect answer deducted 2 points. At the end of the round, the scores were as follows:

Alice: 75 points
Bob: 60 points
Charlie: 80 points
David: 70 points

In the second round, the participants had to solve 5 challenging problems. Each correct answer awarded 10 points. The scores after the second round were as follows:

Alice: 125 points
Bob: 100 points
Charlie: 110 points
David: 100 points

Finally, in the third round, the participants had to solve a single extremely difficult problem. The correct answer awarded 50 points. The scores after the third round were as follows:

Alice: 175 points
Bob: 150 points
Charlie: 160 points
David: 150 points

Thus, at the end of the Maths Olympiad of 2020 at Animal Planet, the rankings of the representatives were as follows:

1. Alice: 175 points
2. Charlie: 160 points (tied with David)
3. David: 160 points (tied with Charlie)
4. Bob: 150 points
