Question
In an objective test, Kavya attempted 70%  of the
questions. Out of those attempted, she answered 80%  correctly. Each correct answer gives 3 marks  and each wrong answer deducts 1 mark . If her score is 308 , find the total number of questions.Solution
ATQ, Let the total number of questions = 100x Number of questions attempted = 100x * 70/100 = 70x Number of correct answers = 70x * 80/100 = 56x Number of wrong answers = 70x – 56x = 14x According to the question, 56x * 3 – 14x * 1 = 308 168x – 14x = 308 154x = 308 x = 2 Total number of questions = 100 * 2 = 200
