Directions: Each of the questions below consists of a question and some statements are given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:
» Explain it
C
Following the common explanation we can say the data in statement II and III are sufficient to answer the question, while the data in statement I is not sufficient to answer the question.

Hence, the correct answer is option C.

Common Explanation:

From Statement I:

Reference:

Depa is the daughter-in-law of Kana, Aman is grandson of Shiv, who is the father of Siya.

Inference:

We will use the above information in two parts.

Part 1:

Depa is the daughter-in-law of Kana.

Using the above information we can create a following blood chart:
 
          

Part 2:

Aman is grandson of Shiv, who is the father of Siya.


Since, we don't have any information about the sixth person i.e. 'Daya', thus we can't determine the youngest person of the family.

Thus, data statement in I alone is not sufficient to answer the question.

From Statement II:

Reference:

Depa is not youngest while Shiv is the eldest.

Inference:

Using the given information we can say that Depa is not youngest in family but Shiv is the eldest in the family.

Here, anyone among Siya, Daya, Kana and Aman can be the youngest in the family.

Thus, data statement in II alone is also not sufficient to answer the question.

From Statement III:

Reference:

Siya is the father of Daya, who is grandson of Shiv. Kana is the wife of Aman’s son and Daya’s father.

Inference:

Using the given information we can create a following blood chart.


Here also we don't have any information regarding the sixth person of the family i.e. 'Depa'. Thus we can't determine the youngest person of the family.

Thus, data statement in III alone is again not sufficient to answer the question.

From Statement I and II:

Reference:

Depa is the daughter-in-law of Kana, Aman is grandson of Shiv, who is the father of Siya.

Depa is not youngest while Shiv is the eldest.


Inference:

From statement I we have the information that,

Depa is the daughter-in-law of Kana.

Using the above information we can create a following blood chart:


And, from statement II we have the information that,

Depa is not youngest in family but Shiv is the eldest in the family. But still we don't have any information about the sixth member i.e. 'Daya.'

So, either Aman or Daya could be the youngest member of the family.

Thus, data in statement I and II are not sufficient to answer the question.

From Statement II and III:

Reference:

Depa is not youngest while Shiv is the eldest.

Siya is the father of Daya, who is grandson of Shiv. Kana is the wife of Aman’s son and Daya’s father.


Inference:

From statement II we have the information that,

Depa is not youngest in family but Shiv is the eldest in the family.

And, from statement III we have the following information,


Since Depa is not the youngest person of the family as per statement II, so the person in the third generation must be the youngest one. Therefore it is clear that Daya is the youngest person of the family.

Thus, data in statement II and III are sufficient to answer the question.

C
Following the common explanation we can say that data in statement II and III are sufficient to answer the question, while the data in statement I is not sufficient to answer the question.

Hence, the correct answer is option C.

Common Explanation:

From Statement I:

Reference:

There is only one floor between the floors on which floor Rupa and Raj are living. Hina is living on an even numbered floor.

Inference:

Using the given information we can say that Rupa and Raj are living at the gap of 1 floor and Hina lives on one of the floors among 2, 4 and 6.

But, here we cannot surely say that who among them lives on the ground floor.

Here, data statement in I alone is not sufficient to answer the question.

From Statement II:

Reference:

Gopi is not living on an even numbered floor. Raj is living on an even numbered floor. Raj is not living on the top floor.

Inference:

Using the given information we can say that Raj is living on either floor 2 or 4 and Gopi is living on one of the floors among 1, 3 and 5.

But, here we cannot surely say that who among them lives on the ground floor.

Here, data statement in II alone is also not sufficient to answer the question.

From Statement III:

Reference:

Rani is living on an odd numbered floor. There are two floors between the floor on which Rani and Hina are living. Gopi is living immediately above Rupa.

Inference:

Using the given information we can say that Rani lives on one of the floors among 1, 3 and 5, there are two floors between Hina and Rani, and Gopi lives immediately above Rupa.

But, here we cannot surely say that who among them lives on the ground floor.

Here, data statement in III alone is again not sufficient to answer the question.

From Statement I and II:

Reference:

There is only one floor between the floors on which floor Rupa and Raj are living. Hina is living on an even numbered floor.

Gopi is not living on an even numbered floor. Raj is living on an even numbered floor. Raj is not living on the top floor.


Inference:

Using the information given in both statements I and II we can say that Raj is living on either floor 2 or 4, Hina lives on one of the floors among 2, 4 and 6, Gopi is living on one of the floors among 1, 3 and 5 and Rupa and Raj are living at the gap of 1 floor.

At this point there are three possible scenarios in which we can use the above hints accordingly.
 
  Possibility 1 Possibility 2 Possibility 3
Floor Person Person Person
6 Hina Hina Rupa
5      
4 Rupa Raj Raj
3      
2 Raj Rupa Hina
1      
 
Here, any of the persons among Gopi, Damu and Rani can be living on ground floor.

Thus, data in statement I and II are not sufficient to answer the question.

From Statement II and III:

Reference:

Gopi is not living on an even numbered floor. Raj is living on an even numbered floor. Raj is not living on the top floor.

Rani is living on an odd numbered floor. There are two floors between the floor on which Rani and Hina are living. Gopi is living immediately above Rupa.


Inference:

Using the information given in both statements II and III we can say that Raj is living on either floor 2 or 4, Gopi and Rani lives on one of the floors among 1, 3 and 5, there are two floors between Hina and Rani, and Gopi lives immediately above Rupa.

At this point we can create a following floor plan with the above information.
 
Floor Person
6 Hina
5 Gopi
4 Rupa
3 Rani
2 Raj
1 Damu
 
Here, Damu is living on ground floor.

Thus, data in statement II and III are sufficient to answer the question.

From Statement I and III:

Reference:

There is only one floor between the floors on which floor Rupa and Raj are living. Hina is living on an even numbered floor.

Rani is living on an odd numbered floor. There are two floors between the floor on which Rani and Hina are living. Gopi is living immediately above Rupa.


Inference:

Using the information given in both statements I and II we can say that Rani lives on one of the floors among 1, 3 and 5, Hina lives on one of the floors among 2, 4 and 6 there are two floors between Hina and Rani, Rupa and Raj are living at the gap of 1 floor and Gopi lives immediately above Rupa.

At this point there are three possible scenarios in which we can use the above hints accordingly..
 
  Possibility A Possibility B Possibility C
Floor Person Person Person
6 Damu Gopi Hina
5 Rani Rupa Gopi
4 Gopi Hina Rupa
3 Rupa Raj Rani
2 Hina Damu Raj
1 Raj Rani Damu
 
Here, any of the persons among Raj, Damu and Rani can be living on ground floor.

Thus, data in statement I and III are not sufficient to answer the question.

Four persons Jay, Ram, Anu and Roy are sitting around a circular table. Are all of them facing towards the centre of table?

I.
If Ram is sitting second to the right of Roy. Roy is facing centre. Anu is sitting immediate right of Ram and Roy.

II. If Jay is sitting immediate left of Ram. Anu is not sitting immediate of Jay. Anu is sitting immediate right of Roy.

III. If Roy is sitting immediate of Jay and Anu. Ram is sitting immediate left of Jay. Anu is sitting immediate left of Roy.
» Explain it
A
Following the common explanation we can say the data in statement I alone or in the statement II alone or in the statement III alone is sufficient to answer the question.

Hence, the correct answer is option A.

Common Explanation:

From Statement I:

Reference:

Ram is sitting second to the right of Roy. Roy is facing centre. Anu is sitting immediate right of Ram and Roy.

Inference:

Using the given information we can fix the position of Ram, Anu and Roy on the circular table as follows:


Here, in the above circular arrangement Ram is facing away from the centre of the table.

So, we can say that all of them are not facing towards the centre of table.

Here, data statement in I alone is sufficient to answer the question.

From Statement II:

Reference:

Jay is sitting immediate left of Ram. Anu is not sitting immediate of Jay. Anu is sitting immediate right of Roy.

Inference:

Using the given information there are two possible scenarios in which we can fix the position of Jay, Anu and Roy on the circular table as follows:
 

Here, in the above circular arrangement either Ram or Roy is facing away from the centre of the table.

So, we can say that they all are not facing towards the centre of table.

Here, data statement in II alone is also sufficient to answer the question.

From Statement III:

Reference:

Roy is sitting immediate of Jay and Anu. Ram is sitting immediate left of Jay. Anu is sitting immediate left of Roy.

Inference:

Using the given information there are two possible scenarios in which we can fix the position of Jay, Anu, Ram and Roy on the circular table as follows:
 
  

Here, in the above circular arrangement either Anu, Jay or Roy is facing away from the centre of the table.

So, we can say that they all are not facing towards the centre of table.

Here, data statement in III alone is again sufficient to answer the question.

There are five students Veta, Viji, Veer, Viki and Vinu in a class.

Who scored the second lowest marks?
 
Statement I: Veta got the same marks as Viji. Veer got lower marks than exactly two of them. Viki is not the highest or lowest scorer and didn’t get the same marks as any of them.
 
Statement II: Veta and Viji are the only ones who got the same marks. Viki scored more than either Veer or Vinu. Only two of them scored more than Veer.
» Explain it
D
 
Statement I : Statement II :
 

From statements,
Arrangement: Descending order from left to right

Veta = Viji,

Case: 1
Veta = Viji Veer Viki Vinu
 
 
Case: 2
Vinu Viki Veer Veta = Viji
 
 
not sufficient to answer the question
 

From statements,
Arrangement: Descending order from left to right

Veta = Viji,

Case: 1
Veta = Viji Veer Viki Vinu
 
 
Case: 2
Vinu Viki Veer Veta = Viji
 
not sufficient to answer the question
 
Statement I and Statement II By, combining two statements,

Note: Both statements same information is given in different manner

Case: 1
Vinu Viki Veer Veta = Viji
 
 
Case: 2
Veta = Viji Veer Viki Vinu
 
 
not sufficient to answer the question
 

The data given in both statements I and II together are not sufficient to answer the question
 
 
 Hence option D is correct.
