# Coding and decoding explanations with examples and practice questions

Coding and decoding in logical reasoning involves translating a message or pattern from one form to another based on a specific rule or pattern. The goal is to decipher the hidden message or pattern by understanding the encoding rule. Here's an explanation in simple terms, along with 20 multiple-choice questions and answers:

Concept Explanation:

Coding: Coding is the process of converting a message or pattern into a different form using a specific rule or pattern.

Decoding: Decoding is the process of converting the coded message or pattern back into its original form using the same rule or pattern.

Rules or Patterns: The coding and decoding rules can vary, such as shifting letters in the alphabet, replacing letters with numbers, or using mathematical operations.

Coding and Decoding Questions:

Question: If "CAT" is coded as "FBD," how is "DOG" coded?

Answer: "DOG" is coded as "GRJ." Explanation: Each letter in the word "CAT" is replaced by the letter that comes three positions after it in the alphabet. Therefore, "DOG" is coded as "GRJ."

Question: If "APPLE" is coded as "CRRNG," how is "BANANA" coded?

Answer: "BANANA" is coded as "DCPCPC." Explanation: Each letter in the word "APPLE" is shifted by two positions to the right in the alphabet. Therefore, "BANANA" is coded as "DCPCPC."

Question: If "SUN" is coded as "VWP," how is "MOON" coded?

Answer: "MOON" is coded as "OQQP." Explanation: Each letter in the word "SUN" is replaced by the letter that comes two positions after it in the alphabet. Therefore, "MOON" is coded as "OQQP."

Question: If "RAT" is coded as "UAW," how is "BAT" coded?

Answer: "BAT" is coded as "EDW." Explanation: Each letter in the word "RAT" is replaced by the letter that comes three positions after it in the alphabet. Therefore, "BAT" is coded as "EDW."

Question: If "PEN" is coded as "TJS," how is "INK" coded?

Answer: "INK" is coded as "LRN." Explanation: Each letter in the word "PEN" is replaced by the letter that comes four positions after it in the alphabet. Therefore, "INK" is coded as "LRN."

Question: If "CUP" is coded as "FXS," how is "MUG" coded?

Answer: "MUG" is coded as "QXL." Explanation: Each letter in the word "CUP" is replaced by the letter that comes six positions after it in the alphabet. Therefore, "MUG" is coded as "QXL."

Question: If "HAT" is coded as "MBW," how is "CAP" coded?

Answer: "CAP" is coded as "GED." Explanation: Each letter in the word "HAT" is replaced by the letter that comes four positions after it in the alphabet. Therefore, "CAP" is coded as "GED."

Question: If "RED" is coded as "VHG," how is "BLUE" coded?

Answer: "BLUE" is coded as "HPYJ." Explanation: Each letter in the word "RED" is replaced by the letter that comes five positions after it in the alphabet. Therefore, "BLUE" is coded as "HPYJ."

Question: If "SKY" is coded as "VNK," how is "SUN" coded?

Answer: "SUN" is coded as "VZR." Explanation: Each letter in the word "SKY" is replaced by the letter that comes three positions after it in the alphabet. Therefore, "SUN" is coded as "VZR."

Question: If "GUN" is coded as "KXQ," how is "COW" coded?

Answer: "COW" is coded as "GSZ." Explanation: Each letter in the word "GUN" is replaced by the letter that comes four positions after it in the alphabet. Therefore, "COW" is coded as "GSZ."
