Letter Coding Decoding - Rearrangement
Introduction : Coding is a system of signals. This is a method of transmitting information in the form of codes or signals without it being known by a third person.The person who transmits the code or signal, is called the sender and the person who receives it, is called the receiver. Transmitted codes or signals are decoded on the other side by the receiver—this is known as decoding.
Example 1 : In a certain code language, ‘GIVE’ is written as ‘VIEG’ and ‘OVER’ is written as ‘EVRO’. How will ‘DISK’ be written in that same code ?
(A) SIDK (B) KISD (C) KDSI (D) SIKD
Answer : (D)
Solution : We need to find a definite rule to get the answer. This can be done as shown below :
Example 2 : If "DEMOCRATIC" is written as "EDMORCATCI", how "CONTINUOUS" will be written in the same code?
(A) OCTNNIOUSU (B) OTCNINUOUS (C) OCNTNIUOSU (D) OTNCINUOSU
Answer : (C)
Solution : As there is no definite pattern between "DEMOCRATIC" and the code "EDMORCATCI". So, use the following rule to find the code for "CONTINUOUS" :
Example 3 : In a certain code, ‘REFRIGERATOR’ is coded as ‘ROTAREGIRFER’. Which words from the following would be coded as ‘NOITINUMMA’?
(A) ANMOMIUTMI (B) AMNTOMUIIN (C) AMMUNITION (D) NMMUNITIOA
Solution : The pattern can be seen from the given diagram. All the alphabets are reversed in the word "REFRIGERATOR" to get "ROTAREGIRFER". Applying this same principle on the word "NOITINUMMA", we get AMMUNITION. Hence the code for "AMMUNITION" is "NOITINUMMA".
Example 4 : In a certain code language, 'HUMAN’ is written as ‘MUHNA’ and ‘RESOURCES’ is written as ‘SERRUOSES’. How will ‘BIODEGRADABLES’ be written in that same code ?
(A) SELBADARGEDIO (B) OIBGEDABLESRAD (C) OIBGEDDARLBASE (D) OIBDEGRADABLES
Answer : (C)
Solution : In the above question, HUMAN contains 5 letters in it, RESOURCES contains 9 letters. Pair of 3 are formed , but, if there are no 3 letters left then pair of two are formed.
In case of HUMAN,
HUM = MUH
AN = NA
In case of RESOURCES,
RES = SER
OUR = RUO
CES = SEC
Similarly, in case of BIODEGRADABLES,
BIO = OIB
DEG = GED
RAD = DAR
ABL = LBA
ES = SE
So, the answer is OIBGEDDARLBASE.
Example 5 : In a certain code language, 'GIRL’ is written as ‘IGRL’ and ‘BIOCHEMISTRY’ is written as ‘EIIOBCHMSTRY’. How will ‘SUBSTANCES’ be written in that same code ?
(A) UAESBSTANCES (B) AEUSBSTNCES (C) UEASBSTNCS (D) AEUSBSTNCS
Answer : (D)
Solution : In the above question, GIRL contains 4 letters in it, BIOCHEMISTRY contains 12 letters.
Only vowels are arranged first but according to there codes , then consonants are written as it is.
In case of GIRL, on I is vowel which is written first.
In case of BIOCHEMISTRY, I, O, E, I, are the vowels which are placed according to increasing codes. Then consonants are written.
Now, in case of SUBSTANCES, U, A, E , all are vowels which are placed according to increasing codes. Then consonants are written.
So, the answer is AEUSBSTNCS.
Example 6 : In a certain code, ‘EUROPEON’ is written as ‘UEOREPNO’. How would ‘CONSERVATION’ be written in that code?

When I have not joined Abhyas Academy, my skills of solving maths problems were not clear. But, after joining it, my skills have been developed and my concepts of science and SST are very well. I also came to know about other subjects such as vedic maths and reasoning.
