Coding Decoding Questions FOR Bank Exams with Detailed Solutions

Sol.
Logic here is:

Split the word into first two letters, middle letter, and last two letters.
Rule:
1st & 2nd letters → Opposite letters according to the English alphabet.
Middle letter → +2 shift
Last two letters → Opposite letters according to the English alphabet.
Apply to MELON:
M → N (opposite)
E → V (opposite)
L → N (+2)
O → L (opposite)
N → M (opposite)
NVNLM
Now, interchange the first two letters with each other and the last two letters with each other, while the middle letter remains in the same position.
Thus, the final code is VNNLM

Logic: 

Rule Used:
Take the opposite letter of each alphabet (Atbash rule: A↔Z, B↔Y, C↔X, etc.)
Then:
Left side letter → Opposite letter − 1
Right side letter → Opposite letter + 1
Apply this in a cross (X) manner
(Follow the same patterns in REST.)

Logic here is:

Logic here is: The place value of consonants is added by 2 and the place value of vowels are added by 5

Break it letter by letter:
R (consonant) → R + 2 = T
I (vowel) → I + 5 = N
G (consonant) → G + 2 = I
H (consonant) → H + 2 = J
T (consonant) → T + 2 = V
RIGHT → TNIJV
