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.
