Q: If CEJQ is coded as XVQJ, then BDIP will be coded as:

a.WURQ

b.YWRK

c.WUPI

d.YWPI

 Answer (b)

Explanation:    The first 13 letters of the alphabet are coded by the 13 letters of the alphabet in reverse, i.e.                                 = A B C D E F G H I J K L M (first 13 letters)

                                      = Z Y X W V U T S R Q P O N (13 letters in reverse)

                                          It is obvious from the above coding scheme that:

                                             B = Y, D = W, I = R and K = P or P = K

                                       Therefore, B D I P will be coded as Y W R K.
