In Mixed number coding type of questions, a few groups of numbers each coding a certain short message, are given. Through a comparison of the given coded message, taking two at a time, the candidate is required to find the number code for each word and then formulate the code for the message given.
In a certain code, '289' means 'read from paper'; '276' means 'tea from field' and '85' means 'wall paper'. Which of the following is the code for 'tea' ?
In the first and second statements, the common digit is '2' and the common word is 'from'.
So, '2' is the code for 'from'.
In the first and third statements, the common code digit is '8' and the common word is 'paper'.
So, '8' is the code for 'paper'.
Clearly, in the second statements, either '7' or '6' may be the code for 'tea'.
