Coding and Decoding questions:

Answer:a. QFO

To find the code for "PEN" based on the given coding scheme (GUN → HVO), you can apply the same pattern to each letter:

• G → H (Move one letter forward in the alphabet)
• U → V (Move one letter forward in the alphabet)
• N → O (Move one letter forward in the alphabet)

Applying this pattern to "PEN":

• P → Q (Move one letter forward in the alphabet)
• E → F (Move one letter forward in the alphabet)
• N → O (Move one letter forward in the alphabet)

So, according to the given coding scheme, "PEN" is coded as "QFO."

Answer:C. 55914

Explanation:

To find the code for 46823 based on the given coding scheme (35796 → 44887), we can analyze the pattern. Let's look at each digit individually:

• 3 → 4 (Increment by 1)
• 5 → 4 (Decrement by 1)
• 7 → 8 (Increment by 1)
• 9 → 8 (Decrement by 1)
• 6 → 7 (Increment by 1)

Applying this pattern to 46823:

• 4 → 5 (Increment by 1)
• 6 → 5 (Decrement by 1)
• 8 → 9 (Increment by 1)
• 2 → 1 (Decrement by 1)
• 3 → 4 (Increment by 1)

So, according to the given coding scheme, 46823 is coded as 55914.

Answer:a. KMHJEGDF

Explanation: B = AC It means original letters can be inserted in
O = NP between the two coded letters Y=XZ
So L=KM,
I=HJ ,
F=EG
and E = DF.

Answer:b. 61

Explanation: S I S T E R        U N C L E
5 3 5 3 0 1        8 4 6 7 0
B O Y        S O N
1 2 9        5 2 4

Answer:c. 38, 30

Explanation: The difference between S and Lis
6 x 2 = 12 + 16 = 28
. The difference between L and F is
5 x 2 = 10 + 28 = 38
The difference between V and P is
5 x 2 = 10 + 10 = 20
and the difference between P and J is also 5 x 2 = 10 + 20 = 30.

Answer:c. data are inadequate

Explanation: 4= good
7 = Picture
and 2 and 9 = are and faint respectively.

Answer:c. YMN

Explanation: X V       N L I I       I I ABCDEFGHIJKLMNOPQRSTUVWXYZ It means C = X or third from left and III from right and O = L or 15th from left and 15th from right. M = N or 13th from left and 13th from right, E = V or th from left and Vth from right.

Answer:c. GHIRT

Explanation: If you observe carefully then the coded word GNORW has same letters as in the original word. So, if we go by elimination method then option b is eliminated here itself. Now if we look at the pattern of coding, it can be observed that all the letters of WRONG are arranged in Ascending Order. So, in the same way, RIGHT will be coded as GHIRT. There can be same type of question asked but instead of ascending, the words can be in descending order.

Answer:a. MDOLD

Explanation: Grouping. So here grouping of letters is done. First 2 letters- M and O are grouped and last 2 letters S and E are grouped. After grouping, +1 is added and the position of the letters is interchanged. Like in MO group, +1 is added so the result will be NP and then the letters are interchanged and so the result for 1st group will be PN. Same for the second group and the middle odd letter is as it is.

Answer:d. 46

Explanation: This is an interesting question and you will often get confuse. Because even if you try to add the numeric value you won’t get the answer. But here reverse numeric value concept is used. So, in this question the reverse numeric values are considered and added. C=24, A=26, P=11. 24+26+11=61 and the same logic for PEN. P=11, E=22 and N=13. Answer=46
