A student has to get 40% marks to pass in an examination. Suppose he gets 30 marks and fails by 30 marks, then what are the maximum marks in the examination?

- 100
- 120
- 150
- 300

### Answer

Let maximum marks in the examination be x.

Pass marks = 40% of x

After getting 30 marks, the student fails by 30 marks. So, passing marks are 60.

40% of x = 60

x = 150

**The correct option is C.**
