Out of the 150 students of School X, 40 students have opted for only F...
Steps 1 & 2: Understand Question and Draw Inferences
We are given that there are 150 students in a school. Out of these 150 students, 40 have opted only for French as an extra subject.
There are 30 students who haven’t opted for any of German or French as the extra subject.
Let’s say:
X = Number of students who opted for both the subjects
Y = Number of students who opted only for German as the extra subject
So, the above information can be represented as follows:
The sum of the numbers in the four zones of the Venn diagram will be equal to the total number of students.
Thus,
40 + X + Y + 30 = 150
We get:
X + Y = 80 ……….. (1)
The question asks us to find the value of Y.
Step 3: Analyze Statement 1
The total number of students opting for at least one subject out of German and French is 120
This means,
40 + X + Y = 120
Or, X + Y = 80
As shown in equation (1), we already have this information. However, since we don’t have the value of X, we can’t find the value of Y.
Hence, Statement 1 is not sufficient to answer the question: What is the value of Y?
Step 4: Analyze Statement 2
The number of students who opted for both German and French is one-third of the number of students who opted for neither of the two subjects
Per this statement,
X=1/3(30)=10
By plugging in the value of X in Equation (1), we get,
Y = 70
Hence, Statement 2 alone is sufficient to answer the question: What is the value of Y?
Step 5: Analyze Both Statements Together (if needed)
Since Statement 2 alone is sufficient to answer the question, we don’t need to perform this step.
Answer: Option (B)

Given:
- Total number of students in School X = 150
- Number of students who have opted for only French = 40
- Number of students who have opted for neither German nor French = 30
To find:
- Total number of students who have opted for only German
Statement 1:
- The total number of students opting for at least one subject out of German and French is 120.
This statement alone is not sufficient to determine the number of students who have opted for only German. We know that the total number of students opting for at least one subject is 120, but we don't know how many of those students have opted for only German.
Statement 2:
- The number of students who opted for both German and French is one-third of the number of students who opted for neither of the two subjects.
Let's assume the number of students who opted for both German and French is x. Then, the number of students who opted for neither German nor French is 3x.
We are given that the number of students who opted for neither German nor French is 30, so we can write the equation:
3x = 30
x = 10
Therefore, the number of students who opted for both German and French is 10.
Now, we can calculate the number of students who have opted for only German:
- Total number of students who opted for German = Number of students who opted for both German and French + Number of students who opted for only German
- Total number of students who opted for German = 10 + Number of students who opted for only German
Since the total number of students who opted for German is not given, we cannot determine the number of students who have opted for only German using this statement alone.
Combined statements:
From statement 1, we know that the total number of students opting for at least one subject is 120.
From statement 2, we know that the number of students who opted for both German and French is 10.
Using this information, we can calculate the number of students who have opted for only German:
- Total number of students who opted for German = Number of students who opted for both German and French + Number of students who opted for only German
- Total number of students who opted for German = 10 + Number of students who opted for only German
Since the total number of students who opted for German is not given, we cannot determine the number of students who have opted for only German using these combined statements.
Therefore, statement 2 alone is sufficient to answer the question, but statement 1 alone is not sufficient. Hence, the correct answer is option B.
- Total number of students in School X = 150
- Number of students who have opted for only French = 40
- Number of students who have opted for neither German nor French = 30
To find:
- Total number of students who have opted for only German
Statement 1:
- The total number of students opting for at least one subject out of German and French is 120.
This statement alone is not sufficient to determine the number of students who have opted for only German. We know that the total number of students opting for at least one subject is 120, but we don't know how many of those students have opted for only German.
Statement 2:
- The number of students who opted for both German and French is one-third of the number of students who opted for neither of the two subjects.
Let's assume the number of students who opted for both German and French is x. Then, the number of students who opted for neither German nor French is 3x.
We are given that the number of students who opted for neither German nor French is 30, so we can write the equation:
3x = 30
x = 10
Therefore, the number of students who opted for both German and French is 10.
Now, we can calculate the number of students who have opted for only German:
- Total number of students who opted for German = Number of students who opted for both German and French + Number of students who opted for only German
- Total number of students who opted for German = 10 + Number of students who opted for only German
Since the total number of students who opted for German is not given, we cannot determine the number of students who have opted for only German using this statement alone.
Combined statements:
From statement 1, we know that the total number of students opting for at least one subject is 120.
From statement 2, we know that the number of students who opted for both German and French is 10.
Using this information, we can calculate the number of students who have opted for only German:
- Total number of students who opted for German = Number of students who opted for both German and French + Number of students who opted for only German
- Total number of students who opted for German = 10 + Number of students who opted for only German
Since the total number of students who opted for German is not given, we cannot determine the number of students who have opted for only German using these combined statements.
Therefore, statement 2 alone is sufficient to answer the question, but statement 1 alone is not sufficient. Hence, the correct answer is option B.
