MCQ: Data Sufficiency- 2 - SSC CGL MCQ

Checking Statement I:

Using the above references, we get the information:
 
_ > _ > _ > _ > Tarak > _

Vijay > Komal > Rishi

Here, we cannot merge the above inferences to form a single arrangement of the order of heights of these persons.

So, we cannot say who among these persons is the tallest.

Hence, data in statement I alone is not sufficient.

Checking Statement II:

Using the above references, we get the information:

Rishi > Tarak/Sanjay

So, we cannot say who among these persons is the tallest.

Hence, data in statement II alone is not sufficient.

Checking Statements I and II:

Using the above reference, we get the following arrangement:

Usha > Vijay > Komal > Rishi > Tarak > Sanjay

Clearly, both statements I and II together are sufficient to answer the question.

Hence, Option D is correct.

Checking Statement I:

Since there is no information about Monika's rank. Therefore, Rahul's rank cannot be determined.

Clearly, Statement I alone is not sufficient to answer the question.

Checking Statement II:

Aditi's rank and Monika's rank is not given. Therefore, Rahul's rank cannot be determined.

Clearly, Statement II alone is not sufficient to answer the question.

Checking Both statement I and II:

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

Clearly, Both statements I and II  is not sufficient to answer the question.

Hence, Option D is correct.

Checking Statement I:

Using the above references, we get the following cases:

Case 1:

Case 2:

 Since there is no clear information about the position of Ramesh so, we cannot say anything about the person who sits on the immediate left of Ramesh.

Clearly, Statement I alone is not sufficient to answer the question.

Statement II:

Using the above references, we get the following cases:

 
Clearly, Statement II alone is not sufficient to answer the question.

Checking both statements I and II:

Using the both statements, we get the following arrangement:

Clearly, Both statement I and II are sufficient to answer the question.

Hence, Option D is correct.

Checking Statement I:

Akhil > Chetan > Ekta/Bina

But we don't know whether Dinesh or Chetan is the second tallest.

Hence data in statement I is not sufficient to answer the question.

Checking Statement II:

Akhil > Dinesh/Chetan> Dinesh/Chetan > Bina > Ekta

But we don't know whether either Dinesh or Chetan is the second tallest.

Hence data in statement II is not sufficient to answer the question.

Checking both statements I and II:

Akhil > Dinesh/Chetan> Dinesh/Chetan > Bina > Ekta

Still, we cannot determine the second tallest person.

Hence data in both statements I and II is not sufficient to answer the question.

Hence, Option D is correct.

Checking Statement I:

As per hints, following arrangements can be formed

H > J > K > I > G > F

Clearly H earns the maximum amount.

Hence data in statement I is sufficient to answer the question.

Checking Statement I:

As per hints, following arrangements can be formed

H > J > K > I > G > F

Clearly H earns the maximum amount.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

Hence, Option C is correct.

From Statement 1:

No one has exam after S.

Three people has exam between S and R.

N has exam before R.

M has exam after Thursday.

W has exam before B.

From, this statement, we get:

 So, from this statement, N has exam immediately after B.

From Statement 2:

Two people have exam before R, who has exam immediately after S.

B has exam after R but not on Saturday.

N has exam immediately after H.

From this statement, M has exam immediately after B.

So, either statement 1 or statement 2 alone is sufficient to answer the question.

Hence option C is correct.

From Statement 1:

N is the son of L, who is married to O.

L has only one child.

H is the father-in-law of N.

O is the mother-in-law of Q.

From, this statement, we can arrange the family tree as possible-

So, from this statement, we determine that L is father-in-law of Q.

From Statement 2:

H has only one son and one daughter, one of which is N.

Q is the sister of N, who is the son of M.

M is the mother-in-law of O, who is the mother of L.

From this statement, we can draw the family tree as follow:

So, from this statement, we cannot determine how L is related to Q, because here we don’t know the gender of L.

Hence option A is correct.

From Statement 1:

We have, D moved a distance of 40m towards north.

From there he turns to the right and walked for 30m and reached school.

Here, we can’t determine in which direction is D’s home from the school.

From Statement 2:

We have, D is facing south. He turns right and walk for 100m.

After that he turned to the left walk for 50m and reach home.

Here, we can’t determine in which direction is D’s home from the school.

Hence option B is correct.

From Statement 1:

We have, S visits the zoo immediately before Q, who visits on Friday.

Two persons visit between S and V.

From the statement, we cant find who visits zoo on sunday.

From Statement 2:

We have, only two people visits zoo after R.

V visits zoo two days before R.

Three people visits zoo between V and Q.

 From the statement, Q visits the zoo on Sunday.

Hence option D is correct.

From Statement 1:

We have, S sits third to the right of N and third to the left of M.

 From the statement, M sits at the extreme right end.

From Statement 2:

We have, X sits in the middle of the line.

Y sits second to the right of X.

Z sits fifth to the left of W, who is the neighbor of Y.

From the statement, W sits at the extreme right end.

Hence option B is correct.

Checking Statement I:
Using the above references, we get the following arrangement:

Since there is no information about the position of Bhanu so we cannot find the person who sits on the immediate right of Bhanu.

Hence, data in statement I alone is not sufficient.
Checking Statement II:
Using the above references, we get the following arrangement:

Clearly, Prakash sits on the immediate right of Bhanu.

Hence, data in statement II alone is sufficient.

Hence, Option B is correct.

Checking Statement I:

Using the above references, we get the following arrangement:

Clearly, D was born in July.

Hence data in statement I is sufficient to answer the question.

Checking Statement II:

Using the above references, we get the following arrangement:

Clearly, D was born in July.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

Hence, Option C is correct.

Checking Statement I:

Using the above references, we get the following arrangement:

Kamal > Rohit > Priya/Johny > Suresh > Tinku

Clearly Kamal is the oldest among all.

Hence data in statement I is sufficient to answer the question.

Checking Statement II:

Using the above references, we get the following arrangement

Kamal > Priya > Suresh > Johny > Tinku > Rohit

Clearly Kamal is the oldest among all.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

Hence, Option C is correct.

From Statement 1:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘dnj msk ahw swe’ means ‘May be next time’

Here, we can’t find the code for ‘Time’.

From Statement 2:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘vnm msk qqa oqa’ means ‘Careful you are next’

Here, we can’t find the code for ‘Time’.

From Statement1 and Statement2:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘dnj msk ahw swe’ means ‘May be next time’

In the same code language ‘vnm msk qqa oqa’ means ‘Careful you are next’

Here, we can’t find the confirm code for ‘Time’.

Hence option D is correct.

From Statement 1:

C = X ≤ D ≥ R

From the statement, the conclusion H < D is not followed because H is absent.

From Statement 2:

R > Z = O > H

From the statement, the conclusion H < D is not followed because D is absent.

From Statement1 and Statement2:

We have, C = X ≤ D ≥ R > Z = O > H

From the statement, H < O = Z < R ≤ D, the conclusion H < D is followed.

Hence option D is correct.
