whereas Pooja scored 72% marks in the same exam and scored 70 marks more than the passing marks. Find the maximum marks of the exam.Solution
ATQ; Let the maximum marks of the exam be ‘100x’ Marks scored by Neha = 100x × 0.52 = ‘52x’ Marks scored by Pooja = 100x × 0.72 = ‘72x’ According to question: 52x + 90 = 72x – 70 Or, 72x – 52x = 90 + 70 Or, 20x = 160 Or, x = 8 Therefore, maximum marks of the exam = 100x = 100 × 8 = 800
