1. A candidate scoring 25% marks in an examination fails by 30 marks while another candidate who score 50% marks gets 20 marks more than the minimum pass marks. what is the minimum pass mark?
- A. 60
- B. 60
- C. 60
- D. 60
Answer: Option B
Explanation:
Let the maximum marks be 'x'.
Then, according to the question.
(25 % of x) + 30 = (50 % of x) - 20
⇒ x/4 + 30 = x/2 - 20
⇒ (x/4) - (x/2) = - 20 - 30
⇒ (x - 2x)/4 = - 50
⇒ - x/4 = - 50
⇒ - x = - 200
⇒ x = 200
So, the maximum marks are 200.
Minimum passing marks are = x/4 + 30 = 200/4 + 30 = 50 + 30 = 80 marks
Minimum passing marks are 80
