If a minimum of 40% marks in Chemistry is required to pursue higher studies in Chemistry, how many students will be
eligible to pursue higher studies in Chemistry?

Accepted Answer

The table shows the number of students scoring marks in different ranges for Chemistry. The requirement is a minimum of 40% marks in Chemistry to be eligible for higher studies. Since the total marks are 50, 40% of 50 is 20 marks. Therefore, students scoring 20 and above are eligible.

From the table, the number of students scoring 20 and above in Chemistry is 66. However, this includes those scoring 20 and above, 30 and above, and 40 and above. But the table is cumulative, so 66 students scored 20 and above.

But the question asks for students scoring at least 40% marks, which is 20 marks or more. So, the eligible students are 66.

However, the options given are 66, 25, 45, and 21. The correct answer is 66.

Rechecking the question: It says minimum 40% marks in Chemistry, which is 20 marks. So, students scoring 20 and above are eligible, which is 66 students.

Hence, the correct answer is 66.
