If 'HELLO' is coded as '12345', 'WORLD' is coded as '67890', and 'LOW' is coded as '345', what is the code for 'OLD'?

A. 678

B. 345

C. 890

D. 123

E. None of the above

Answer: A. 678

The common letters in 'WORLD' and 'LOW' are 'O' and 'L'. 'O' = 6 and 'L' = 3. 'OLD' has 'O' = 6 and 'D' = 0, so the code is '678'.
