In an MBA entrance exam, a candidate attempts X questionscorrectly and...
Consider the solution to the previous question.
X + Y + unattempted questions = total questions
X + Y + unattempted questions = total questions
5 + 5 + unattempted questions = 20 unattempted questions = 10
Hence, option 3.

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 (equation 1)
- Each correct answer fetches 1.5 marks
- Each incorrect answer deducts 0.5 marks
- Total number of questions = 20
To find:
- Number of questions not attempted
Solution:
Let's solve the given problem step by step:
Step 1: Formulate the equations:
- The number of questions attempted correctly (X) can be written as X = 2Y - 5 (equation 1)
- The total number of questions attempted (X + Y) should be equal to the total number of questions, which is 20.
Step 2: Substitute the value of X from equation 1 into the second equation:
X + Y = 20
(2Y - 5) + Y = 20
3Y - 5 = 20
3Y = 25
Y = 25/3
Step 3: Calculate the value of Y:
Y = 25/3 ≈ 8.33
Since the number of attempted questions cannot be in decimal, we need to round it to the nearest whole number. Thus, Y = 8.
Step 4: Calculate the value of X:
X = 2Y - 5
X = 2(8) - 5
X = 16 - 5
X = 11
Step 5: Calculate the number of questions not attempted:
Number of questions not attempted = Total number of questions - Number of questions attempted
Number of questions not attempted = 20 - (X + Y)
Number of questions not attempted = 20 - (11 + 8)
Number of questions not attempted = 20 - 19
Number of questions not attempted = 1
Therefore, the student did not attempt 1 question.
Conclusion:
The student did not attempt 1 question out of the total 20 questions.
- X = number of questions attempted correctly
- Y = number of questions attempted incorrectly
- X = 2Y - 5 (equation 1)
- Each correct answer fetches 1.5 marks
- Each incorrect answer deducts 0.5 marks
- Total number of questions = 20
To find:
- Number of questions not attempted
Solution:
Let's solve the given problem step by step:
Step 1: Formulate the equations:
- The number of questions attempted correctly (X) can be written as X = 2Y - 5 (equation 1)
- The total number of questions attempted (X + Y) should be equal to the total number of questions, which is 20.
Step 2: Substitute the value of X from equation 1 into the second equation:
X + Y = 20
(2Y - 5) + Y = 20
3Y - 5 = 20
3Y = 25
Y = 25/3
Step 3: Calculate the value of Y:
Y = 25/3 ≈ 8.33
Since the number of attempted questions cannot be in decimal, we need to round it to the nearest whole number. Thus, Y = 8.
Step 4: Calculate the value of X:
X = 2Y - 5
X = 2(8) - 5
X = 16 - 5
X = 11
Step 5: Calculate the number of questions not attempted:
Number of questions not attempted = Total number of questions - Number of questions attempted
Number of questions not attempted = 20 - (X + Y)
Number of questions not attempted = 20 - (11 + 8)
Number of questions not attempted = 20 - 19
Number of questions not attempted = 1
Therefore, the student did not attempt 1 question.
Conclusion:
The student did not attempt 1 question out of the total 20 questions.
