Question: In a certain code, 'XYZ' means 'We are friends'. Which letter stands for 'We'? Statements: 'PYN' means 'They are classmates'. 'ZMS' means 'We love them'. 'PX' means 'Hello friends',

Only II
Only I and III
All I, II and III
Either I only or II only
None of these

Correct Answer: None of these

Explanation:

To find the code for 'we', we need to have any of the following:

(i) 'We are friends' should have only 'We' common with another statement, as in II;

(ii) 'We are friends' should have only 'are' and 'friends' common with another single or two statements, as in I and III. Thus, we need Either II only or I and III only.
