Aptitude Test Question:

In an aptitude test, a student must answer 80% of the questions correctly to pass. If a student has answered 24 questions and has answered 18 questions correctly, will the student pass the test? What is the minimum number of questions in the test?

To determine if the student will pass the test:

Percentage of correct answers = (Number of correct answers / Total number of questions) x 100

Percentage of correct answers = (18 / 24) x 100 = 75%

Since the student must answer 80% of the questions correctly to pass, the student will not pass the test with a 75% score.

Let x be the minimum number of questions in the test:

80% of x = 24 correct answers

0.8x = 24

x = 24 / 0.8

x = 30

Therefore, the minimum number of questions in the test is 30 for the student to pass.
