Question 661. In a coding language, the letters of the English alphabet are arranged in such a manner that all the vowels are put in the end and the remaining letters are arranged from the first letter onwards. The rearranged alphabets are used to denote the position occupied by letters in the original alphabets. What is the code of META?
Answer: Option D. -> QGYB
The original and rearranged letter sequences are as shown :
ABCDEFGHIJKLMNOPQRSTUVWXYZ
BCDFGHJKLMNPQRSTVWXYZAEIOU
Thus, the code for META is QGYB.
The original and rearranged letter sequences are as shown :
ABCDEFGHIJKLMNOPQRSTUVWXYZ
BCDFGHJKLMNPQRSTVWXYZAEIOU
Thus, the code for META is QGYB.
Answer: Option D. -> ERIRNY
Each letter in the word is moved thirteen steps forward to obtain the corresponding letter of the code.
Each letter in the word is moved thirteen steps forward to obtain the corresponding letter of the code.
Answer: Option C. -> HMUHTJCMF
Each of the first four letters in the word is moved one step backward, while each of the last five letters is moved one step forward to obtain the corresponding letter of the code.
Each of the first four letters in the word is moved one step backward, while each of the last five letters is moved one step forward to obtain the corresponding letter of the code.
Answer: Option D. -> W
Each letter in the given message is moved two steps backward to obtain the corresponding letter of the code.
The last letter of the third word in the given sentence is Y, which shall be coded as W.
Each letter in the given message is moved two steps backward to obtain the corresponding letter of the code.
The last letter of the third word in the given sentence is Y, which shall be coded as W.
Answer: Option A. -> ROAAKNM
The word is first written twice and the letters at the even positions in the word so obtained, form the code.
The word is first written twice and the letters at the even positions in the word so obtained, form the code.
Answer: Option E. -> None of these
The letters in the first half and second half of the word are written in the reverse order to obtain the code.
Thus, we have :
MYSORE => MYS/ORE => SYM/ERO => SYMERO.
The letters in the first half and second half of the word are written in the reverse order to obtain the code.
Thus, we have :
MYSORE => MYS/ORE => SYM/ERO => SYMERO.
Answer: Option D. -> L
Divide the word into five sets of two letters each and label these sets from 1 to 5. Then the code contains these sets in the order 5, 4, 3, 2, 1 with the letters of sets 5, 3, 1 written in a reverse order.
Thus, we have :
PO PU LA RI SE => ES RI AL PU OP
1 2 3 4 5 => 5 4 3 2 1
Divide the word into five sets of two letters each and label these sets from 1 to 5. Then the code contains these sets in the order 5, 4, 3, 2, 1 with the letters of sets 5, 3, 1 written in a reverse order.
Thus, we have :
PO PU LA RI SE => ES RI AL PU OP
1 2 3 4 5 => 5 4 3 2 1
Answer: Option C. -> QDCKTIPV
The last four letters of the word are written in the reverse order, followed by the first four letters in the same order. In the group of letters so obtained, each of the first four letters is moved one step backward while each of the last four letters is moved one step forward to get the code.
Thus, we have :
SHOULDER => SHOU/LDER => REDL/SHOU => QDCK/TIPV
The last four letters of the word are written in the reverse order, followed by the first four letters in the same order. In the group of letters so obtained, each of the first four letters is moved one step backward while each of the last four letters is moved one step forward to get the code.
Thus, we have :
SHOULDER => SHOU/LDER => REDL/SHOU => QDCK/TIPV
Answer: Option A. -> IDUJLAIC
The word is divided into groups of four letters each and then the letters in each group are written in a reverse order.
The word is divided into groups of four letters each and then the letters in each group are written in a reverse order.
Answer: Option C. -> JCBUTCDRHK
The letters in the first half and second half of the word are written in the reverse order and in the group of letters so obtained, each letter in the first half is moved one step forward while that in the second half is moved one step backward, to get the code.
Thus, we have :
STABILISED => STABI/LISED => IBATS/DESIL => JCBUT/CDRHK
The letters in the first half and second half of the word are written in the reverse order and in the group of letters so obtained, each letter in the first half is moved one step forward while that in the second half is moved one step backward, to get the code.
Thus, we have :
STABILISED => STABI/LISED => IBATS/DESIL => JCBUT/CDRHK
