Identify common words between sentences and their corresponding common codes; green appears in sentences 1 and 3, sharing the code ta.
Analyze shared words and codes
Equation 1: green apple sweet = ta lo mi. Equation 2: red apple fresh = ku lo pe. Equation 3: green mango fresh = ta si pe.
Identify codes for individual words
Comparing 1 and 3, 'green' is common, and 'ta' is the common code, so green = ta. Comparing 1 and 2, 'apple' is common, and 'lo' is the common code, so apple = lo. Comparing 2 and 3, 'fresh' is common, and 'pe' is the common code, so fresh = pe.
Final combination
Since green = ta and apple = lo, the code for green apple is ta lo.
A: ku lo contains 'ku' which belongs to red, making it incorrect. B: mi si contains 'mi' which belongs to sweet and 'si' which belongs to mango, both incorrect. D: ta pe contains 'pe' which belongs to fresh, making it incorrect.
C is correct because the common word green is coded as ta and the common word apple is coded as lo based on the overlapping set analysis.
In word-substitution coding, always map the words shared across at least two sentences first to isolate the specific variables.
