In a class of boys A is 34th from left and 27th from the right those who have passed the exam. If the ratio of pass to fail candidates is 4 : 1; then what is the total number of students in class?
Answer & explanation
Correct answer: option 3
Total passed students = 34 + 27 – 1

Pass : Fail = 4 : 1

Total students = 60 + 15 ⇒ 75
