Question 51

There is a lot of interest in the first five ranks for Class XI students. One student guessed the rank order as Ankita, Bhagyashree, Chanchal, Devroopa and Esha. Later upon announcement of the results, it was found that not only did he get each student out off her true position, none of the students in his ranking correctly followed her immediate predecessor. Another student guessed Devroopa, Ankita, Esha, Chanchal and Bhagyashree. Even his guess was wrong. It was found that he had 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?

Solution

We have been given that A, B, C, D and E are not holding the 1, 2, 3, 4 and 5 ranks, respectively.

Also that two of the positions in the arrangement DAECB are correct and the other two follow their immediate predecessors.

The only arrangement satisfying both these conditions is EDACB.

Thus, option A is the correct answer.
