SSC CHSL Coding Decoding

In a certain code, the position of each letter in the word is replaced by a number: A/E/I/O/U = 1, B/C/D/F/G = 2, H/J/K/L/M = 3, N/P/Q/R/S = 4, T/V/W/X/Y/Z = 5. What is the code for 'DESK'?

In a code, every alternate letter starting from the first is shifted backward by 1 position (A→Z, B→A, C→B, etc.), while other letters remain unchanged. What is the code for 'PENCIL'?

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. What is the code for the word 'HELLO'?

In a code language, each letter is replaced by the letter that is 2 positions before it in the English alphabet, with A wrapping to Y and B wrapping to Z. What is the code for 'GIFT'?

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 coding system, each letter is replaced by the letter that comes 3 positions after it in the English alphabet (with Z wrapping to C, Y wrapping to B, X wrapping to A). Using this rule, what is the code for the word 'HELLO'?

In a certain code, each letter is replaced by the letter that comes 2 positions before it in the English alphabet (with wrapping: A→Y, B→Z). What is the code for 'JUMP'?

In a code language, vowels are replaced by the number representing their position in the vowel sequence (A=1, E=2, I=3, O=4, U=5), and consonants remain unchanged. Using this rule, what is the code for the word 'FRIEND'?

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. If the word 'HELLO' is coded using this rule, what is the code?

In a code language, each word is written by reversing it and then replacing each vowel with the next vowel in sequence (A→E, E→I, I→O, O→U, U→A). What is the code for 'MAKE'?

In a code, the position of each letter in the word is noted (1st, 2nd, 3rd, etc.), and each letter is replaced by the letter that is as many positions forward in the alphabet as the letter's position in the word. For example, in 'BAT': B (position 1) → C (1 position forward), A (position 2) → C (2 positions forward), T (position 3) → W (3 positions forward). Result: 'CCW'. Using this rule, what is the code for 'HELP'?

In a code, each letter is replaced by a number based on its position in the alphabet (A=1, B=2, ..., Z=26). Then, each number is multiplied by 2. What is the numeric code for 'BRAIN'?

In a certain code, each letter is replaced by the letter that comes 3 positions after it in the English alphabet. For example, A → D, B → E, and so on. Z wraps around to C. Using this rule, what is the code for the word 'LOGIC'?

In a code, consonants are replaced by the consonant that comes 2 positions after them in the consonant sequence (B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z), and vowels are replaced by the vowel that comes 1 position after them in the vowel sequence (A, E, I, O, U). For example, B→D, A→E. What is the code for 'BRIGHT'?

In a certain code, each letter is assigned a number: A=1, B=2, C=3, ..., Z=26. A word is encoded by replacing each letter with its number, then summing all numbers. If the sum is greater than 50, subtract 50; if the sum is less than or equal to 50, add 10. What is the code for 'CAT'?

In a code, vowels (A, E, I, O, U) 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 'DREAM'?

In a code, 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 'FRIEND'?

In a certain code, the position of each letter in the word is numbered from left to right starting at 1. Each letter is replaced by the letter at position (original position + 2) in the alphabet, wrapping around if necessary. What is the code for 'MASTER'?

In a certain code, each letter is replaced by the letter that comes 3 positions after it in the English alphabet. For example, A→D, B→E, C→F, and so on. Z wraps around to C. Using this code, what is the encoding of the word 'LOGIC'?

A hybrid code uses this rule: consonants are shifted forward by 3 positions in the alphabet, vowels are replaced by their position number (A=1, E=5, I=9, O=15, U=21), and then the entire result is reversed. For example, 'BAT' → B(+3=E), A(=1), T(+3=W) → E-1-W → W-1-E. What is the code for 'STUDENT'?
