Identify common words across sentences and eliminate their corresponding codes until only the target word remains.
Identify common words across sentences and eliminate their corresponding codes until only the target word remains.
Analyze Statement 1 and 2
Statement 1: 'sky is blue' тЖТ 'mn op qr'. Statement 2: 'blue and white' тЖТ 'st qr uv'. The common word is 'blue' and the common code is 'qr'. Thus, blue = qr.
Analyze Statement 2 and 3
Statement 2: 'blue and white' тЖТ 'st qr uv'. Statement 3: 'white and bright' тЖТ 'uv st wx'. Common words are 'and' and 'white'. Common codes are 'st' and 'uv'. Thus, 'and/white' are 'st/uv'.
Identify Bright
Since Statement 3 is 'white and bright' тЖТ 'uv st wx' and we know 'white' and 'and' map to 'uv' and 'st', the only remaining word 'bright' must map to the remaining code 'wx'.
B: 'uv' corresponds to either 'white' or 'and'. C: 'st' corresponds to either 'white' or 'and'. D: 'qr' corresponds to 'blue'.
A is correct because by identifying that 'blue' is 'qr' and both 'white' and 'and' are represented by 'st' and 'uv', the only remaining code 'wx' must represent the word 'bright'.
In coding-decoding, always list the statements one below another and strike out common words on both sides to isolate the unique code.
