Important Points 

→  Relationship between two entities is shown with the help of certain  symbols which establish relation . In the directions , the actual relation of symbol is given  which you need to note down.

→ In statements  Random English alphabets are given between which the above given symbols are inserted. So, this results in establishment of relation between the random alphabets. 

→ You have to note down the  relation (either multiplication , addition, greater than,less than ) between given statement alphabets by referring to information given in directions. After this step only you should proceed to conclusions step .

→ In Conclusions 4 random mixed alphabets and symbols is given for which you have to check whether the relations holds true according to statement. 

→  You job is done once you  check all 4 given conclusion for there correctness . Depending on how many conclusions are found correct choose the options.

Example :

Directions: In the following questions, the symbols % , $, # and @ are used with the following meaning as illustrated below :

A % B means  A is neither smaller than nor equal to B

A  B  means A is not greater than B  ( blank space between A and B)

A $ B means A is not smaller than B

A# B means A is neither greater than nor equal to B

A@B means A is neither greater than nor smaller than Q .

1. Statements:

P  Q , Q#R , R@S , S%T

Conclusions:

I) R≥T      II) Q≤T      III) R>T     IV) P<S

1) Only I is true

2)Only III is true

3) Only II and III are true

4) Only III and IV are true .

Solution :

Explanation :

Step 1: From the directions we can interpret the symbols relationship. So note down them on paper as 

% →  >   

$  →  ≥

# → < 

@ → =

Blank → ≤

Step 2: Write the given statement by including the relation in place of symbol 

 P ≤ Q <  R = S> T

Step 3: Now check each given conclusion for its trueness

1 R≥T     X ( Actually R >T)

2 Q≤T     X (Actually we cannot determine relationship between them as we can see < and > symbols between them)

3 R >T   ✓ (As R=S , R=S>T can be written as R>T. Hence given conclusion is true.)

4 P< S    ✓
