MCQ: Data Sufficiency- 1 - SSC CGL MCQ

From Statement I:
A is the sister of C, who is the daughter-in-law of M. M has only two children.
From, this statement, we can arrange the family tree as possible-

So, from this statement, we cannot determine the brother-in-law of A.
From Statement II:
O is the wife of M, who is the sibling of Q. B is the only male child of O.
From this statement, we can draw the family tree as follow:

So, from this statement, we cannot determine the brother-in-law of A.
From Statement I and Statement II together:
A is the sister of C, who is the daughter-in-law of M. M has only two children. O is the wife of M, who is the sibling of Q. B is the only male child of O.
From this statement, we can draw the family tree as follow:

So, from both statements, B is the brother-in-law of A.
Hence option D is correct.

From Statement I:
M is shorter than only P. K is taller than L and N.
Case1: P > M > K > N > L
Case2: P > M > K > L > N
Here, we cannot determine who is the shortest, either L or N is the shortest person. Also, we don’t know the position of O here.
From Statement II:
We have, M is shorter than both P and L. K is shorter than P but taller than L. O is shorter than both K and M. P is not tallest.
N > P > K > L > M > O
Here, O is the shortest person.
Hence option B is correct.

From Statement I:
O runs faster than N but slower than L. P runs slower than N but is not slowest runner.
L > O > N > P > M
Here, N is the third faster runner.
From Statement II:
M runs slower than N. L runs faster than N and P. O runs faster than only M.
L > N/P > P/N > O > M
Here, either N or P is the third faster runner.
So, the data in Statement I alone is sufficient to answer the question while the data in Statement II is not sufficient to answer the question.
Hence option A is correct.

From Statement 1:
H sits to the immediate right of D.
Two persons sit between D and F.
A is an immediate neighbour of M, who sits to the immediate right of F.

So, H sits to the immediate left of N.
The data in Statement I alone is sufficient to answer the question.
From Statement 2:
F and N are immediate neighbours and M sits immediate right of F.
A sits third to the left of N.
Here, we can not determine who sits immediate left of N.

Hence, option A is the correct answer.

From Statement 1:
A sits to the immediate left of C.
D sits second to the right of A.

From the statement, we cannot determine who sits second to the right of B.
From Statement 2:
D sits immediately between E and B.
B sits to the immediate left of A.

From the statement, C sits second to the right of B.
Hence option C is correct.

From Statement 1:
A’s rank is five ranks below H's rank, whose rank is 19^th from the bottom.

Here, A’s rank is 10^th from the top.
From Statement 2:
A’s rank is seven ranks above F's rank, whose rank is 11^th from the bottom.

Here, A’s rank is 6^th from the top.
Hence option C is correct.

Checking Statement I:

Since there is no data given about Player and Champion, therefore, No player is Champion can not be derived.

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

Checking Statement II:

Statement II is the converse statement of the required conclusion.

Clearly, Statement II alone is sufficient to answer the question.

Hence, Option B is correct.

Checking Statement I:
Using statement I, we do not get any relation between car and cycle.
Therefore, the conclusion cannot be derived using statement I alone.
Checking Statement II:
Using statement II, we do not get any relation between car and cycle.
Therefore, the conclusion cannot be derived using statement II alone.
Checking both statements I and II:
Using both statements I and II, we get the following diagram:

Since some cycles are trains and no train is buses and all cars are buses, therefore, some cycles are not cars is definitely true.
Since the required conclusion can be derived by using statements I and II together.
Hence, Option D is correct.

Checking Statement I:

Codes for truck and train cannot be found out.

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

Checking Statement II:

Codes for truck and train cannot be found out.

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

Checking both statements I and II together:

Code for truck is 110 and code for train is 115.

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

Hence option D is correct.

Checking Statement I:
As per the hints, the following arrangements can be formed

Hence data in statement I is sufficient to answer the question.
Checking Statement II:
As per the hints, the following arrangements can be formed

Hence data in statement II is not sufficient to answer the question.
Hence, Option A is correct.

Checking Statement I:

Here, as Kirti correctly remembers that her birthday is in the second half of the year, so her birthday is in July or August or September or October or November or December.

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

Checking Statement II:

Here, as Kirti’s father correctly remembers that her birthday is after 31st October but before 1st December, so we can say that Kirti’s birthday is in November.

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

Hence, Option B is correct.

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

Clearly, A is sitting immediately left of C.
Hence data in statement I is sufficient to answer the question.
Checking Statement II:
Using the above references, we get the following arrangement:

Hence data in statement II is not sufficient to answer the question.
Hence, Option A is correct.

Checking Statement I:

Using the above reference, we get the following arrangement:

Clearly, W is sitting second to the right of U.

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

Checking Statement II:

Using the above references, we get the following arrangement:

Clearly, W is sitting second to the right of U.

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:

Code for the word dove cannot be found.

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

Checking Statement II:

Code for the word dove cannot be found because it is not mentioned in statement II.

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

Checking Statement both statements I and II together:

The code for dove is 'hv'.

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

Hence option D is correct.

Checking Statement I:

As per hints, following arrangements can be formed

A > E > B > C/D > D/C

Here in the above statements, clearly A is the heaviest person.

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

Checking Statement II:

As per hints, following arrangements can be formed

A > E > B/C > C/B

Since, there is no information about D, so statement II alone is not sufficient.

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

Hence, Option A is correct.
