Question

A teacher gave her class two exams; 60% of the class passed the second exam, but only 48% of the class passed both exams. What percent of those who passed the second exam also passed the first exam? Select one: a. 80% b. 12% c. 30% d. 48%

Answer 1

the answer is (a) 80%.

Explanation:

Let's assume that there were 100 students in the class.

Then, from the given information, we know that:

60 students passed the second exam.

48 students passed both exams.

To find the percentage of those who passed the second exam and also passed the first exam, we can use the formula:

(number of students who passed both exams / number of students who passed the second exam) x 100%

Substituting the values we have:

(48 / 60) x 100% = 80%

Therefore, the answer is (a) 80%.
