Did the Student Qualify in the Examination?

In an examination, a student must answer 70% of the questions correctly. If a student answered 28 questions correctly out of the first 40, did the student qualify?

To determine if the student qualified, we need to calculate the minimum number of questions needed to answer correctly to meet the 70% requirement.

Let's calculate:

Total number of questions = 40

70% of 40 = 0.7 x 40 = 28

The student answered 28 questions correctly out of 40, which meets the 70% requirement.

Hence, the student has qualified in the examination.
