SSC MTS Coding Decoding

In a certain code, consonants are shifted forward by 1 position (B→C, C→D, etc.), and vowels are shifted backward by 1 position (E→A, I→E, O→I, U→O, A→U). What is the code for 'SMILE'?

In a code language, each letter is replaced by the letter 2 positions before it in the alphabet (C→A, D→B, E→C, etc.). Letters A and B are coded as Y and Z respectively. What is the code for 'DESK'?

In a code, the first and last letters of a word are swapped, and all middle letters remain in their original positions. What is the code for 'GARDEN'?

In a code, each letter is replaced by a number: A=1, B=2, C=3, ..., Z=26. What is the numerical code for the word 'CAT'?

In a certain code, each letter is replaced by the letter that comes 3 positions after it in the English alphabet. For example, A is coded as D, B is coded as E, and so on. Using this rule, what is the code for the word 'HELP'?

In a code language, vowels are replaced by the next vowel in sequence (A→E, E→I, I→O, O→U, U→A), and consonants remain unchanged. What is the code for 'BRAIN'?

In a certain code, each letter is replaced by the letter that comes 3 positions ahead in the alphabet. For example, A→D, B→E, C→F. Using this rule, what is the code for the word 'HELLO'?

In a code, vowels are replaced by the next number (A→1, E→2, I→3, O→4, U→5) and consonants are replaced by the previous letter in the alphabet. For example, B→A, C→B. What is the code for 'BRAIN'?

In a certain code, the position of each letter in the word is noted, and the letter is replaced by the letter at the opposite position from the end of the alphabet. For example, A (1st position in alphabet) → Z (26th position), B (2nd) → Y (25th). What is the code for 'LOGIC'?

In a code, every consonant is replaced by the consonant that comes 2 positions after it in the alphabet (skipping vowels), and every vowel is replaced by the vowel that comes 2 positions after it (A→E, E→I, I→O, O→U, U→A). What is the code for 'SYSTEM'?

In a code, letters are replaced by numbers based on their position in the alphabet, but every 3rd number is doubled. For example, C (3rd letter) → 6 (3×2), F (6th letter) → 12 (6×2). What is the code for 'FACE'?

A code uses the rule: consonants are shifted forward by 3 positions in the alphabet, vowels are replaced by the number of vowels that appear before them in the word (starting count from 1). What is the code for 'ELEPHANT'?

In a complex code, the word is first split into alternating groups (1st letter alone, 2nd-3rd letters together, 4th letter alone, 5th-6th letters together, etc.), then each group is reversed, and finally all groups are concatenated in reverse order. What is the code for 'PROBLEM'?

In a hybrid code, letters in odd positions (1st, 3rd, 5th, etc.) are shifted backward by 2 in the alphabet, and letters in even positions (2nd, 4th, 6th, etc.) are replaced by their position number multiplied by 2. What is the code for 'GARDEN'?

In a coding system, each letter is replaced by the number representing its position in the alphabet, then each number is reversed (written backwards). For example, A=1 becomes 1, but when reversed it stays 1; B=2 becomes 2; K=11 becomes 11 reversed to 11. What is the code for the word 'MOTHER'?

In a mirror-image coding system, each letter is replaced by its mirror position from the opposite end of the alphabet (A↔Z, B↔Y, C↔X, etc.), and then the entire word is written in reverse order. What is the code for 'BRAIN'?

A code reverses the word, then replaces each letter with the letter that comes 5 positions after it in the alphabet (with Z wrapping to E, A wrapping to F, etc.). What is the code for 'SYSTEM'?
