Out of 110 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 to the students who passed the exam without distinction.

Correct Answer: 5 : 4
The total number of students who passed the exam = 110 – 20 = 90 students The number of students passing the exam with distinction = 20% of 90 = 18 students The remaining students = 90 – 18 = 72 students The ratio required = 90 : 72 = 5 : 4
