In an examination Prakash secured 30% of the total marks and failed by 20 marks. Kashish secured 52% of the total marks and secured 24 marks more than minimum pass percentage. Find the pass percentage of marks.
Explanation:
Let total marks be x, and let pass marks be p.
Prakash: 0.3x = p – 20 …(1)
Kashish: 0.52x = p + 24 …(2)
(2) – (1)
⇒ 0.22x = 44
⇒ x = 200 and p = 80.
Pass % = 80/200 = 0.4 or 40%
Hence, option (c).
