In Mixed letter coding type of questions, three or four complete messages are given in the coded language and the code for a particular word is asked. To analyse such codes, any two messages bearing a common word are picked up. The common code word will mean that word. Proceeding smilarly by picking up all possible combinations of two, the entire message can be analysed.
In 'nitco sco tingo' stands for 'softer than flower';
'tingo rho mst' stands for 'sweet flower fragrance' and
'mst sco tmp' stands for 'sweet than smile',
what would 'fragrance' stands for ?
In the first and second statements, the common code word is 'tingo' and the common word is 'flower'.
So, 'tingo' means 'flower'.
In the second and third statements, the common code word is 'mst' and the common word is 'sweet'.
So, 'mst' stands for 'sweet'.
Thus, in the second statement, 'rho' stands for 'fragrance'.
