How many boys students are there in the class ?I.65%girls students are...
Statement I: 65% girls students are there in the class
Statement II: The number of boys students is half that of girls
To determine the number of boys students in the class, we need to know the total number of students in the class. However, neither statement provides this information.
Let's analyze each statement separately:
Statement I alone:
We are given that 65% of the students in the class are girls. However, without knowing the total number of students, we cannot determine the number of boys students. For example, if there are 100 students in the class, then 65% of them would be girls, which means there would be 35 boys students. However, if there are 200 students in the class, then 65% of them would be girls, which means there would be 70 boys students. Therefore, statement I alone is not sufficient to answer the question.
Statement II alone:
We are given that the number of boys students is half that of girls. Again, without knowing the total number of students, we cannot determine the number of boys students. For example, if there are 10 girls students, then there would be 5 boys students. However, if there are 20 girls students, then there would be 10 boys students. Therefore, statement II alone is not sufficient to answer the question.
Combining the two statements:
Even when we combine both statements, we still do not have enough information to determine the number of boys students. We know that 65% of the students are girls and that the number of boys students is half that of girls, but without knowing the total number of students, we cannot determine the actual number of boys students. Therefore, the data given in both statements I and II together are not sufficient to answer the question.
In conclusion, neither statement alone nor the two statements together provide enough information to determine the number of boys students in the class. Hence, the correct answer is option D.
