In an examination, the maximum possible score is N while the pass mark is 45% of N. A candidate obtains 36 marks, but falls short of the pass mark by 68%. Which one of the following is then correct?
Explanation:
Passing marks = 45% of N
As 36 marks are short of the pass marks by 68%, it means the cadidate got (100 - 68 = ) 32% of the passing marks.
⇒ 36 = 32% of 45% of N
∴ 36 = 0.32 × 0.45 × N
∴ N = 360.32×0.45 = 250
Hence, option (c).
