In an examination paper of 5 questions, 5% of the candidates answered all of them and 5% none. Of the rest 25% answered only 1 question and 20% answered only 4 questions. If 49/2 % of the entire candidates answered only 2 questions and 200 candidates answered only 3 questions, how many candidates appeared at the examination ?
Answer: B Suppose the total candidates appeared be x. Then, Number of candidates who answered all = 5x/100 Number of candidates who answered none = 5x/100 Remaining = x - 2(5x/100) = 9x/10 Number of candidates answered only 1 question = 25% of 9x/10 = 9x/40. Number of candidates answered 4 question = 9x/10 * 20% = 9x/50 Candidate who answered two questions = 49/2 % of x = 49x/200 Now, 2(5x/100) + 9x/40 + 9x/50 + 49x/200 = x By solving this, we get x = 800. Hence, number of candidates appeared = 800.
