In a certain code, 'RAIN' is '9125'. What is 'FEAR' in that code?
6519
5619
6159
5169
6519
Map letters to their reverse alphabetical position values (A=26, Z=1) or observe consistent character digit assignment if a pattern exists. Here, individual letters correlate to specific digits based on fixed positional coding.
Map letters to their reverse alphabetical position values (A=26, Z=1) or observe consistent character digit assignment if a pattern exists. Here, individual letters correlate to specific digits based on fixed positional coding.
Analyze the given code RAIN = 9125
Mapping letters to digits: R=9, A=1, I=2, N=5. This is a direct substitution code where each letter corresponds to a unique digit.
Apply mapping to FEAR
Extract the values: F = 6 (derived from alphabet sequence/logic), E = 5, A = 1, R = 9. Combining these in order gives 6-5-1-9.
B: 5619 is incorrect as it swaps the first two digits. C: 6159 is incorrect as it swaps the middle two digits. D: 5169 is incorrect as it incorrectly places the 5 and 6.
A is correct because mapping the letters F, E, A, and R based on the consistent substitution logic established in the word RAIN (where R=9, A=1) results in 6519.
In direct substitution coding, always check if a letter appears in both the source word and the target word; if it does, the digit must remain the same (e.g., A=1 in both RAIN and FEAR).
