Question

A student needs to score at least 30% marks to pass a test . If a student gets 135 marks and fall by 15 marks, find the maximum marks of the test

Answer 1

Let the total marks be x

Marks needed to pass = 30/100× x= 3/10x

Marks obtained by student = 135

Marks needed to pass = 135 + 15 = 150

3/10x = 150

x = 150×10/3=500

Maximum marks = 500
