Out of 200 students, 20% failed the exam. Out of the remaining 20% passed the exam with distinction. Find the ratio of the students who passed the exam with distinction to the students who passed the exam without distinction.
Show answer & explanation
Correct answer: B
Explanation
Given:
Total students = 200
Failed = 20%
Of the remaining, 20% passed with distinction.
Failed students = 20% × 200 = 40
Passed students = 200 − 40 = 160
Passed with distinction = 20% × 160 = 32
Passed without distinction = 160 − 32 = 128
Ratio = 32 : 128 = 1 : 4
