examination? Statement I: Pranabh secured 51% marks in the examination and was declared failed by 20 marks. Narendra secured 54% marks in the examination and got 23 marks more than the minimum pass marks. Statement II: Pranabh secured 725 marks in 6 subjects. Statement III: A students will be declared passed if he secures 28.5% of the total marks.Solution
From I According to the question, 51% + 20 = 54% - 23 43 = 3% ∴ 3% = 43 ∴ 51% = 43/3 × 51 = 731 Pass marks = 731 + 20 = 751 Hence, statement I alone is sufficient to answer the question. But II and III are not sufficient to answer the question. But II and III are not sufficient to answer the question because we need more information to find the pass marks.
