Passed student : Failed student
=> ∴failure total student=>4x29x
After admitting 5 more students, Total students = 29x + 5
New failure students = 4x - 2
New ratio
P : F
=> 22y : 3y => 25y
∴failure Total Appeared
=4x−229x+5=3x25y
100x = 50 = 87x + 15
=> 13x = 65
x = 5
∴ Total student appeared in the exam was = 29x + 5 = 150
