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 a certain code language,
(A) 'mxy das zci' means 'good little frock';
(B) 'jmx cos zci' means 'girl behaves good';
(C) 'nvg drs cos' means 'girl makes mischief';
(D) 'das ajp cos' means 'little girl fell'.
Which word in that language stands for 'frock' ?
In statements A and B the common code word is'zci' and the common word is 'good'.
So, 'zci' stands for 'good'.
In statements A and D, the common code word is 'das' and the common word is 'little'.
So, 'das' stands for 'little'.
So, in (A), 'mxy' means 'frock'.
