In a certain code language, ‘LUMP’ is coded as ‘4186’ and ‘BUMP’ is coded as ‘7186’. What is the code for ‘L’ in that language?

Identify common characters in both words and their corresponding code positions to isolate the unique character mapping.
Identify common characters in both words and their corresponding code positions to isolate the unique character mapping.
Analyze the common codes
Given: LUMP = 4186 and BUMP = 7186. Note that U, M, and P are common to both words. The common codes in 4186 and 7186 are 1, 8, and 6. Therefore, the codes 1, 8, and 6 correspond to U, M, and P (in some order).
Isolate the unique letter
By comparing LUMP (4186) and BUMP (7186), the letter L in LUMP corresponds to the digit 4, and the letter B in BUMP corresponds to the digit 7. Since the question asks for the code for L, it is clearly 4.
B: 1 is the code for U, M, or P. C: 8 is the code for U, M, or P. D: 6 is the code for U, M, or P.
A is correct because by subtracting the common code components (186) for (UMP) from the word LUMP (4186), the only remaining digit 4 corresponds uniquely to the letter L.
In comparative coding, always write the words one above the other to quickly identify common characters and their respective digits, saving time on complex logic.
