If 'CAT' is coded as '3-1-20', how is 'DOG' coded?
4-15-7
3-14-6
4-16-8
5-15-7
15-7
Directly replace each letter with its standard 1-based alphabetical position number (A=1 through Z=26).
Directly replace each letter with its standard 1-based alphabetical position number (A=1 through Z=26).
Analyze the Given Code
For the word CAT, map each letter to its alphabetical position: C = 3, A = 1, T = 20. Combining these gives the code 3-1-20.
Apply to the Target Word
Apply the identical positional mapping rule to the word DOG: D = 4, O = 15, G = 7, resulting in the code 4-15-7.
B: Incorrect because 3-14-6 corresponds to C-N-F. C: Incorrect because 4-16-8 corresponds to D-P-H. D: Incorrect because 5-15-7 corresponds to E-O-G.
A is correct because substituting each letter in DOG with its exact 1-based alphabetical position (D=4, O=15, G=7) yields 4-15-7.
Memorize the EJOTY landmark rule (E=5, J=10, O=15, T=20, Y=25) to quickly find letter positions during competitive exams.
