In a code language, the position of letters in a word is reversed, and then each letter is replaced by the letter 2 positions before it in the alphabet (B→Z, C→A, D→B, etc., wrapping around). What is the code for 'PLAY'?

In a certain code language, each letter is replaced by the letter that comes 3 places after it in the English alphabet (A=D, B=E, C=F, ...). Using this rule, what is the code for the word 'COLD'?

In a certain code, each letter is replaced by a number: A=1, B=2, C=3, ..., Z=26. If 'CAT' is coded as 3-1-20, what is the code for 'DOG'?

In a code language, 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. Using this rule, what is the code for 'BRAIN'?

In a certain code, the first and last letters of a word are swapped, and all other letters remain in their original positions. For example, 'BOOK' becomes 'KBOO'. What is the code for 'PENCIL'?

In a code, each letter is replaced by a number: A=1, B=2, C=3, ..., Z=26. If 'CAT' is coded as 3-1-20, what is the code for 'DOG'?

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 the word '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 is coded as D, B is coded as E, and so on. If the word 'HELLO' is coded using this rule, what is the coded word?

In a certain coding system, each letter is replaced by the letter that comes 3 positions ahead of it in the English alphabet. For example, A is coded as D, B is coded as E, and so on. If a letter reaches beyond Z, it wraps around to the beginning (so X→A, Y→B, Z→C). Using this rule, how would the word 'PLAY' be coded?

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 certain coding system, 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 system, what will be the code? Note: After Z, the sequence wraps around to A (i.e., X→A, Y→B, Z→C).

In a code, each letter is replaced by the letter that comes 2 positions before it in the English alphabet (B→Z wraps around). For example, C is coded as A. What is the code for 'FRIEND'?

In a certain 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 'MAKE'?

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, each letter is replaced by the letter that comes 2 positions before it in the English alphabet. For example, C → A, D → B, and so on. Letters A and B wrap around to Y and Z respectively. Using this rule, what is the code for the word 'FRIEND'?

In a code, consonants are coded as the next consonant (B→C, C→D, D→F, F→G, etc., skipping vowels), and vowels are coded as the previous vowel (E→A, I→E, O→I, U→O, A→U). What is the code for 'FRIEND'?

In a code language, consonants are replaced by the next consonant (B→C, C→D, D→F, F→G, G→H, H→J, J→K, K→L, L→M, M→N, N→P, P→Q, Q→R, R→S, S→T, T→V, V→W, W→X, X→Y, Y→Z, Z→B), and vowels remain unchanged. What is the code for 'SMILE'?

In a code, consonants are numbered by their position in the English alphabet, and vowels are represented by symbols: A=@, E=#, I=$, O=%, U=&. What is the code for 'SYSTEM'?

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 'HELLO'?

In a code, the word 'BOOK' is written as '2-15-15-11'. Each letter is replaced by its position number in the English alphabet (A=1, B=2, C=3, ... Z=26). Using this rule, how is the word 'CARE' coded?
