There are 4 main models of questions in Direction Sense Test:

Model 1:

Mr.Ram started from his house and walked straight to the East for 5 Km then turned left walked for 4

Km and again turned left then walked for 5 Km. How much distance Mr.Ram travelled from starting

point.

Answer with Explanation:

Model 2:

Mukesh starting from his house goes 4 Km in the East, and then he turns to his right and goes 3 Km.

What minimum distance will be covered by him to come back to his house?


Model 3:

One morning after sunrise Jhon while going to school met Roja at road crossing. Roja’s shadow was

exactly to the right of Jhon. If they were face to face, which direction was Jhon facing?


In the morning sunrises in the East.

Hence Jhon is facing South.

was going, a road opposite to this direction goest to hospital. The road to the right goes to station. It

the road which goes to station is just opposite to the road which IT-Park, then in which direction to

Priya is the road which goes to IT-Park?


From II it is clear that the road which goes to IT-Park is left to Hema.


Drawing of conclusion/inference.

Premise : All pens are guns

Qualifier Subject Copula Predicate

The Subject Term

The subject is the “main” in a proposition. It is the main argument of the whole proposition, the

actor in the sentence. The subject can be thought of as the “What we are talking about”.

The Predicate Term

The predicate tells us something about the subject. The predicate can be thought as the “What we

are talking about of the subject”.

The Quantifier/Qualifier Term

The extend or number of the subjects.

Ex: All, Some, No, Some note, etc…

The Copula Term

MEDIATE CONCLUSIONS:

Rules (For 2 statements)

Two statements consist of only 3 terms, otherwise no conclusion.

Middle term must be distributer atleast once.

Ex: All pens are guns

All guns are toys

Two negative statements have no conclusion.

Two particular statements have no conclusion.

If a statement is negative then the conclusion should be negative.

If a statement is particular then the conclusion should be particular.

Complementary pairs

If two conclusions are individually wrong, and consisting of same subject and same predicate

then qualifiers are:

All No

All Some Not

Some No

Some Some Not

Then it follows the options of either or.

QUICK LEARNING

ALL (A)

NO (E)

SOME (I)

SOME NOT (O)

A + A = A

A + E = E

E + A = O*

E + I = O*

I + A = I

I + E = O

Step 2: Try to draw diagram, for given relationships which help you to understand clear relationship.

Step 3: Identify the relationships, but nor with names because there are certain names common for

both genders.
