In a certain code language, ‘LION’ is coded as ‘4286’ and ‘COIN’ is coded as ‘7286’. What is the code for ‘L’ in that language?
4
2
8
6
4
Identify the common letters in both words (O, I, N) and their corresponding digits (2, 8, 6) to isolate the unique letter (L).
Identify the common letters in both words (O, I, N) and their corresponding digits (2, 8, 6) to isolate the unique letter (L).
Analyze the commonality
Word 1: LION = 4286. Word 2: COIN = 7286. The letters I, O, N appear in both words. By comparing the codes, we see that 2, 8, and 6 are common to both 4286 and 7286.
Isolate the unique letter
Since 2, 8, and 6 represent I, O, and N, the remaining digit in 'LION' (4) must correspond to the only remaining letter, which is L.
B is wrong because 2 is mapped to I, O, or N; C is wrong because 8 is mapped to I, O, or N; D is wrong because 6 is mapped to I, O, or N.
A is correct because by comparing LION (4286) and COIN (7286), the digit 4 is the only unique value corresponding to the letter L.
In coding-decoding questions, always look for common letters across words to eliminate variables before assigning specific values.
