Identify common words across sentences to isolate codes. Since 'Tax' and 'File' repeat, look for the unique word 'Return' to isolate 'Ri' or 'Zi'.
Analyze Commonality
Compare the three given phrases: 'Pay The Tax' (Gi Si Di), 'File Tax Return' (Ri Zi Si), and 'Keep The Tax File' (Qi Si Gi Zi).
Isolate 'Tax'
The word 'Tax' is present in all three sentences. Looking at the codes, 'Si' is the only code common to all three (Gi Si Di, Ri Zi Si, Qi Si Gi Zi). Therefore, Tax = Si.
Isolate 'File'
The word 'File' is present in the second ('File Tax Return') and third ('Keep The Tax File') sentences. Comparing (Ri Zi Si) and (Qi Si Gi Zi), the common codes are 'Zi' and 'Si'. Since 'Si' is 'Tax', 'File' must be 'Zi'.
A: 'Gi' is 'The' (found in sentences 1 and 3). B: 'Ri' is 'Return' (only in sentence 2). D: 'Qi' is 'Keep' (only in sentence 3).
C is correct because the word 'File' appears in 'File Tax Return' (Ri Zi Si) and 'Keep The Tax File' (Qi Si Gi Zi), and the common code shared by these two excluding 'Tax' (Si) is 'Zi'.
In coding-decoding puzzles, always list the phrases and codes vertically to align common words and codes, making it much faster to spot the overlaps.
