In a mixed number coding system, if 'HELLO' is coded as 23, 18, 15, 14, 12 and 'WORLD' is coded as 25, 22, 19, 18, 16, what is the code for 'GOOD'?
Answer: A. 20, 18, 16, 14
The coding system appears to decrease each letter's position by a consistent value. G(7)-3=4, O(15)-3=12, O(15)-3=12, D(4)-3=1. Thus, the code for GOOD is 20, 18, 16, 14.
