Show answer & explanation
Correct answer: C
Key idea: derive the digit assigned to each letter from the two given coded words, then apply that mapping to GEOLOGY.
G -> 9
E -> 1
O -> 5
L -> 7
R -> 6
Y -> 2
A -> 8
P -> 4
H -> 0
S -> 3
Write the letters of the target word: G E O L O G Y
Replace each letter using the mapping above: G -> 9, E -> 1, O -> 5, L -> 7, O -> 5, G -> 9, Y -> 2
Concatenate the digits to get the final code.
Final code: 9157592
