Map letters to their corresponding positions in the code by observing the word commonalities. Since ROSE=4618 and SEAR=6438, identify common letters 'R', 'E', 'S', 'A'.
Map letters to their corresponding positions in the code by observing the word commonalities. Since ROSE=4618 and SEAR=6438, identify common letters 'R', 'E', 'S', 'A'.
Analyze the first word
ROSE is coded as 4618. This means R=4, O=6, S=1, E=8.
Analyze the second word
SEAR is coded as 6438. Cross-referencing: S=6, E=4, A=3, R=8. Note that these are direct positional substitutions.
Determine the value of O
From the word ROSE (4618), the second letter is O, which corresponds to the second digit 6.
A, B, C are incorrect because the digit 6 represents the letter O in the word ROSE as provided in the problem statement sequence.
D is correct because in the word ROSE, the letter O occupies the second position, which corresponds to the digit 6 in the sequence 4618.
In coding-decoding questions, always check if the digits are a direct positional mapping (as seen here) or a result of an arithmetic operation like position + constant.
