•  #
•  J
•  $
•  H
•  None of these

View Answer

Ans:2
There are 25 elements in the given sequence. 6th element from the right end implies (25 +1 – 6 =) 20th element from the left end.
Now, we have to find out the element which is exactly midway between the 20th and 8th elements from the left end. Thus, the required element’s position in the sequence is 

9. The position of the first and the fourteenth elements in the arrangement are interchanged. Similarly, the second and the fifteenth elements are interchanged, and so on, upto the twelfth and twentyfifth elements. Which element will be second to the right of eighth element from the right end after the rearrangement?

•  P
•  *
•  @
•  I
•  None of these

View Answer

Ans:4
After making changes the arrangement of the elements will be as follows:

Now, we have to find out (8 – 2 =) 6th element from the right end. Hence, the required element is I.
