Question
In an exam, Sunil scored 46% marks and failed by 65
marks whereas Anil scored 66% marks in the same exam and scored 45 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 Sunil = 100x × 0.46 = ‘46x’ Marks scored by Anil = 100x × 0.66 = ‘66x’ According to question: 46x + 65 = 66x – 45 Or, 66x – 46x = 65 + 45 Or, 20x = 110 Or, x = 5.5 Therefore, maximum marks of the exam = 100x = 100 × 5.5 = 550
