Identify common letters in both words (ROAD and DORA) and map their positions to the corresponding digits to isolate the value of A.
Identify common letters in both words (ROAD and DORA) and map their positions to the corresponding digits to isolate the value of A.
Mapping the letters
Compare ROAD (5821) and DORA (1852). Letters R, O, A, D appear in both. R=5, O=8, A=2, D=1.
Verification of positions
In ROAD: R=5, O=8, A=2, D=1. In DORA: D=1, O=8, R=5, A=2. Both confirm A=2.
A: 5 corresponds to R, not A. B: 8 corresponds to O, not A. D: 1 corresponds to D, not A.
C is correct because by comparing the positional mapping of letters in ROAD and DORA, we find that A consistently maps to the digit 2.
In coding-decoding questions with anagrams, look for identical letters appearing in different positions to quickly deduce individual letter values without complex arithmetic.
