Percentages L1

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?

  1. 100
  2. 120
  3. 150
  4. 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.
