In a certain code language, ‘HIDE’ is coded as ‘3795’ and ‘DOWN’ is coded as ‘4287’. What is the code for ‘D’ in the given code language?
4
2
9
7
7
Identify common letters between the given words to check if they share identical digit codes. Since D appears in both HIDE (3795) and DOWN (4287), it must be mapped to the only digit common to both sets, which is 7.
Identify common letters between the given words to check if they share identical digit codes. Since D appears in both HIDE (3795) and DOWN (4287), it must be mapped to the only digit common to both sets, which is 7.
Analyze the given mappings
Word HIDE is coded as 3-7-9-5. Mapping: H=3, I=7, D=9, E=5.
Analyze the second word mapping
Word DOWN is coded as 4-2-8-7. Mapping: D=4, O=2, W=8, N=7.
Re-evaluate based on the common letter
There is a contradiction in direct positional coding. However, looking at the letters provided in both sets, the letter 'D' appears in both 'HIDE' and 'DOWN'. The code for 'HIDE' is 3795 and 'DOWN' is 4287. Since 'D' is in both, we identify the digit shared by both sequences: 7. Therefore, D is coded as 7.
A: 4 is the code for O or W or N depending on positional variation, B: 2 is the code for O or W, C: 9 is the code for I.
D is correct because 7 is the only digit common to both the coded sets (3795 and 4287) where 'D' is the only common letter present in both words.
In coding-decoding, if letters repeat across multiple words with different coded strings, look for the intersection of digits shared by those specific strings to decode common characters.
