In an examination, a student gets 20% of total marks and fails by 30 marks. Another student gets 32% of total marks which is more than the minimum pass marks by 42 marks. The pass percentage is
Solution
Let the total marks be x
and pass marks be z
So, x * 20% = z - 30
x * 32% = z + 42
Implies, x * 12% = 72 or x = 600
z = 150Â
The required ratio = 150/600 = 25%
