In a certain code language, if 'CAT' is '3120', what is 'DOG'?
4157
4167
5157
4147
4157
Write down the A-Z alphabet positional numbers (A=1, B=2, ..., Z=26) and directly substitute the corresponding numbers for each letter in the word.
Write down the A-Z alphabet positional numbers (A=1, B=2, ..., Z=26) and directly substitute the corresponding numbers for each letter in the word.
Analyze the pattern for CAT
Map each letter of CAT to its standard alphabetical position: C=3, A=1, T=20. Concatenating these numbers results in 3120, which matches the given code.
Apply the pattern to DOG
Map each letter of DOG to its standard alphabetical position: D=4, O=15, G=7. Concatenating these numbers (4, 15, 7) results in 4157.
B: 4167 uses an incorrect position for O (16 instead of 15). C: 5157 uses an incorrect position for D (5 instead of 4). D: 4147 uses an incorrect position for G (4 instead of 7).
A is correct because the word DOG is encoded by concatenating the alphabetical positions of D(4), O(15), and G(7) resulting in 4157.
For coding-decoding questions, always check the simplest direct position mapping first (A=1, B=2) before looking for more complex operations like +N or reversed alphabets.
