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.
If 'gnr' tag zog qmp' stands for 'Seoul Olympic Organising Committee';
'hyto gnr emf' stands for 'summer Olympic games' and
'esm sdr hyto' stands for 'modern games history',
what would be the code for 'summer' ?
In the first and second statements, the common code word is 'gnr' and the common word 'Olympic'.
So, 'gnr' means 'Olympic'.
In the second and third statements, the common code is 'hyto' and the common word is 'games'.
So, 'hyto' means 'games'.
Thus, in the second statements, 'emf' means 'summer'.
