Correct Answer – Option 2 : 152
Given:
A student got 20% marks and failed by 72 marks. If he scores 40% marks then he gets 8 marks more than the passing marks.
Concept:
Percentage.
Solution:
Let total marks be 100x
A student scores 20% marks and failed by 72 marks means if he gets 72 marks he would pass
⇒ 20x + 72
A student scores 40% marks and gets 8 marks more than passing marks.
⇒= 40x – 8
Passing marks
⇒ 20x + 72 = 40x – 8
⇒ 20x = 80
⇒ x = 4
Passing marks = 20x + 72
⇒ 80 + 72
⇒ 152
∴ The passing marks is 152.
