Important for :
1
In a certain language:
 
I. ‘They work very hard’ is written as ‘ha ti na li’
II. ‘Work is worship’ is written as ‘pa li sa’
III. ‘They are very spiritual’ is written as ‘mi na ki ha’
 
What is the code word of ‘hard’?
» Explain it
D
From statement I and II, we get:

In these two statements, we can see that only ‘work’ is common and we did not get code for ‘hard’. Hence, these two statements are not sufficient to answer the question.

From statements II and III, we get:

In these two statements, we get nothing common. Hence, these statements are not sufficient to answer the question.

From statements I and III, we get:

In these two statements, we can see that ‘they’ and ‘very’ are common but still we will not get the code for ‘hard’. Hence, these two statements are not sufficient to answer the question.

From statements I, II and III, we get:

‘work’→ li (from statements I and II)

They/very → na/ha (From statements I and III)

Hence, the code for ‘hard’ is ‘ti’

Hence all three are necessary and sufficient to answer the question.

Therefore, option D is correct.

What is the direction of point B with respect to point P?
 
I. The distance between points B and M is the same distance between points Q and J. Point H is 3m to the west of point J. Point Q is 4m to the south of point H.
 
II. Point N is 5m to the west of point Q. Point S is 6m to the north of point N. Point M is 5m to the north of point H. If a person is facing south at point M and he moves 120o in clockwise direction and then turns 30o towards his left, he will face B.
 
III. Point B is 5m to the west of point M. Point Q is 9m to the south of point M. Point N is 5m to the west of point Q. Q is 2m away from P.
» Explain it
C
From statements I and II, we get:


Following the image, we can say that Point B is in north direction with respect to P.

From statements II and III:

As , P is 6m to the north of N which is 5 m to the east of Q. P cannot be 2m away from Q.

From statements I and III, we get:


Following the image we can say that Point B is in north-west direction with respect to P.

Hence, the correct answer would be ‘Statement I and either statement II or statement III together’ are sufficient to answer the question. 

Therefore, option C is correct.

» Explain it
D
From statement I alone:

We have no information about Nandani's rank. Therefore, Rohit's rank cannot be determined.

Thus, the question cannot be answered using Statement I alone.

From statement II alone:

Archana's rank and Nandani's rank is not given. Therefore, Rohit's rank cannot be determined.

Thus, the question cannot be answered using statement II alone.

From statements I and II together:

Ranks are not known for any of them. Thus, Rohit's rank cannot be found.

Thus, the question cannot be answered using both statements I and II together.

Hence, option D is correct.

 
4
There are seven letters W, M, V, N, Q, R, and J. What is the fifth letter from the left end?
 
I. Q is placed fifth to the right of V. W and J are not placed immediately next to either Q or V. Q is placed to the immediate left of R.

II. M is placed to the immediate left of W but is not an immediate neighbour of Q. N is placed second to the left of R.
» Explain it
E
From statement I:

Q is placed fifth to the right of V. Also, Q is placed to the immediate left of R.

Therefore, the arrangement becomes

V __ __ __ __ Q R

Q and J are not placed immediately next to either Q or V.

Therefore, the arrangement becomes

V __ W J __ Q R

or V __ J W __ Q R

However the word formed cannot be determined using this statement.

Thus, the question cannot be answered using Statement I alone.

From statement II: 

M is placed to the immediate left of W, but is not an immediate neighbour of Q. N is placed second to the left of R.

__ M  W __  N  __ R

However, the word formed cannot be determined using this statement.

Thus, the question cannot be answered using Statement II alone.

From statements I and II together:

N is placed to the immediate left of W.

Therefore, the arrangement becomes

V M W J __ Q R

Thus, the question can be answered using both statements I and II together.

Hence, option E is correct.

I. If Rohit who is currently facing North-East, turns 90° clockwise, he would face the same direction as Devesh.
 
II. If Vaibhav who is currently facing North-West, turns 135° anticlockwise, he would face the direction 45° clockwise to the direction Devesh is facing.

Which direction is Devesh facing?
» Explain it
C
Statement I. If Rohit who is currently facing North-East, turns 90° clockwise, he would face the same direction as Devesh.


As per the figure,

Rohit who is facing North-East, turns 90° clockwise. Thus, he will be facing South-East.

It is given that he would face the same direction as Devesh.

Hence, Devesh will also be facing South-East.

Hence, the question can be answered using Statement I alone.


Statement II. If Vaibhav who is currently facing North-West, turns 135° anticlockwise, he would face the direction 45° clockwise to the direction Anusha is facing.


Vaibhav who is facing North-West, turns 135° anticlockwise. Thus, he will be facing South Direction.

It is given that he will face the direction 45° clockwise to the direction as Devesh.

Hence, Devesh will be facing South-Eeast

Hence, the question can be answered using Statement II alone.

Therefore, the question can be answered using either statement I alone or statement II alone.

Hence, the correct answer is option C.
