In this type of questions, some messages are given in the coded language and the code for a particular word or message is asked. To analyse such codes, any two messages bearing a common word are picked up. The common code-word will thus represent that word. Proceeding similarly by picking up all possible combinations of two, the entire message can be decoded and the codes for individual words found.

In a certain coding system, 'rbm-std bro pus' means 'the cat is beautiful', 'tnh pus dim std' means 'the dog brown', 'pus dim bro pus cus' means 'the dog has cat'. What is the code for 'has'?


A) std

B) dim

C) bro

D) cus

Answer:

Option D

Explanation:

 In the third statement, the code word 'pus' occurs twice and the word 'the' also occurs twice. So, the code word for 'the' 'is 'pus'. Now, in the first and third statements, the common code word 'pus' stands for 'the'. So, the other common code word 'bro' stands for the other common word' ie  'cat'. Similarly, in the second and 'third statements, the common code word 'dim' stands for the common word 'dog'.Thus, in the third statement, the remaining code word i.e. 'cus' stands for 'has'.
