Verified Answer
In an MBA entrance exam, a candidate attempts X questionscorrectly and...
Here, X = Y
Y = 2Y - 5 which gives Y = X = 5
A student gets 1.5 marks for each correct answer and loses 0.5 marks for each incorrect answer.
Total marks = 1.5(5) - 0.5(5) = 7.5 - 2.5 = 5.0
Hence, option 2.
Y = 2Y - 5 which gives Y = X = 5
A student gets 1.5 marks for each correct answer and loses 0.5 marks for each incorrect answer.
Total marks = 1.5(5) - 0.5(5) = 7.5 - 2.5 = 5.0
Hence, option 2.

In an MBA entrance exam, a candidate attempts X questionscorrectly and...
Given:
- X = number of questions attempted correctly
- Y = number of questions attempted incorrectly
- X = 2Y - 5
To find:
The student's score when he has the same number of correct and incorrect answers.
Solution:
To find the score, we need to calculate the total marks obtained. The score is calculated based on the following conditions:
- Each correct answer fetches 1.5 marks
- Each incorrect answer deducts 0.5 marks
Step 1: Find X and Y
Given that the student has the same number of correct and incorrect answers, we can set X = Y.
Substituting this in the given equation:
X = 2X - 5
X - 2X = -5
-X = -5
X = 5
Therefore, the student has attempted 5 questions correctly and 5 questions incorrectly.
Step 2: Calculate the score
To calculate the score, we need to multiply the number of correct answers by 1.5 and subtract the number of incorrect answers multiplied by 0.5.
Score = (Number of correct answers * 1.5) - (Number of incorrect answers * 0.5)
= (5 * 1.5) - (5 * 0.5)
= 7.5 - 2.5
= 5.0
Therefore, the student's score is 5.0.
Answer:
The correct answer is option B) 5.0.
- X = number of questions attempted correctly
- Y = number of questions attempted incorrectly
- X = 2Y - 5
To find:
The student's score when he has the same number of correct and incorrect answers.
Solution:
To find the score, we need to calculate the total marks obtained. The score is calculated based on the following conditions:
- Each correct answer fetches 1.5 marks
- Each incorrect answer deducts 0.5 marks
Step 1: Find X and Y
Given that the student has the same number of correct and incorrect answers, we can set X = Y.
Substituting this in the given equation:
X = 2X - 5
X - 2X = -5
-X = -5
X = 5
Therefore, the student has attempted 5 questions correctly and 5 questions incorrectly.
Step 2: Calculate the score
To calculate the score, we need to multiply the number of correct answers by 1.5 and subtract the number of incorrect answers multiplied by 0.5.
Score = (Number of correct answers * 1.5) - (Number of incorrect answers * 0.5)
= (5 * 1.5) - (5 * 0.5)
= 7.5 - 2.5
= 5.0
Therefore, the student's score is 5.0.
Answer:
The correct answer is option B) 5.0.
