A teacher wants to administer a multiple choice (each question having six choices) based quiz of high difficulty level to class of 60 students. The quiz has 60 questions. The probability of selecting the correct answer for good answer for a good student and a brilliant student was 0.2 and 0.25, respectively. The poor students had no learning advantage. The teacher did not want students to cheat but does not have time and resource monitor. All students were seated serially in 10 rows and 6 columns. There is a lot of interest in the first 5 ranks for class XI students. One student guessed the rank order as Anita, Barani, Chanchel, Deva, Esha. Later upon announcement of the results, it was found that not only did he get each student out of her true position, none of the students in his ranking correctly followed her immediate predecessor. Another student guessed Deva, Anita, Esha, Chanchel and Barani. Even his guess was wrong. It was found that he has got two positions correct and two students in his ranking correctly followed their immediate predecessors? Which of the following is true about the correct rank order? |
