MCQ: Data Sufficiency- 3 - SSC CGL MCQ

From Statement I:

From this statement, we get that Madhavi joined the office on 5th, 6th, 7th, 8th or 9th November.

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

From Statement II:

From this statement, we get that Madhavi joined the office on 8th, 9th, 10th or 11th November.

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

Checking both Statement, I and II together:

We can say that Madhavi joined the office either on 8th or 9th November.

Clearly, data in both the statements I and II together is not sufficient to answer question.

Hence, option D is the correct answer.

From Statement I: From this statement, we get the following table,

So, we get that 3 persons are born between L and G.

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

From Statement I: From this statement, we get the following table,

Clearly, data in statement II alone is not sufficient to answer the question as in both cases, two different answers are there. So we can't exactly say which case is correct as per statement II.

Hence, option A is the correct answer.

From Statement I:

'Check is Mandatory' is written as '@wt ^yi *nr' and 'Corporate is expensive' is written as '$bl (ux *nr’.

Hence, Statement 1 alone is not sufficient to answer the question.

From Statement II:

‘Corporate Check Shipping' is written as '^yi (ux #jc' and 'Check praise expensive’ is written as '%hr ^yi $bl'.

Hence, Statement 2 alone is not sufficient to answer the question.

Checking both Statement, I and II together:

Clearly ‘is’ is repeated in statement 1 ('Check is Mandatory' is written as ‘@wt ^yi *nr’ and 'Corporate is expensive' is written as ‘$bl (ux *nr’) and statement 2 ('Check praise expensive’ is written as '%hr ^yi $bl’).

Thus, code for ‘Corporate’ is ‘(ux’.

Clearly, Statement I and Statement II together are necessary to answer the question.

Hence, option D is the correct answer.

From Statement I: From this statement, we get the following arrangement:

Clearly, Statement I alone is not sufficient to answer the question.
From Statement II: From this statement, we get the following arrangement:

Checking both Statement, I and II together:

So, by combining both the statements, we can say A faces U, who sits just right of X.
Clearly, Statement I and Statement II together are necessary to answer the question.
Hence, option E is the correct answer.

From Statement I: From this statement, we get the following inference:

All the vowels are coded as 3rd next letter as per English alphabetical series and the consonants are coded as 2nd previous letter as per English alphabetical series.

So, the code of ‘HEALTHY’ is ‘FHDJRFW’.

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

From Statement II: From this statement, we get the following inference:

All the vowels are coded as 3rd next letter as per English alphabetical series and the consonants are coded as 2nd previous letter as per English alphabetical series.

So, the code of ‘HEALTHY’ is ‘FHDJRFW’.

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

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

Hence, option C is the correct answer.

From Statement I: From this statement, we get the following inference:

As per the figure, Manas who is facing southwest, turns 135° anticlockwise. Thus, he will be facing East.

It is given that he would face the same direction as Tanya. Hence, Tanya will also be facing East.

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

From Statement II: From this statement, we get the following inference:

As per the figure, Dinesh who is facing northeast, turns 90° clockwise. Thus, he will be facing southeast. Also, southeast is 180° to the direction of Tanya. Hence, Tanya will be facing northwest.

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

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

Hence, option C is the correct answer.

From Statement I: From this statement, we get the following inference:

C A _  C _

C E _ C _

C I _ C _

C O _ C _

C U _ C _

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

From Statement II: From this statement, we get the following inference:

We understand that only one letter is between T and H and either A or E is the only vowel used in the word but we cannot form the whole word.

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

Checking both Statement, I and II together:

C A T C H     C A H C T        C E T C H       C E H C T

Here, only ‘CATCH’ is the meaningful word that can be formed.

Hence, option E is the correct answer.

From Statement I: From this statement, we get the following diagram

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

From Statement II: From this statement, we get following diagram

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

Checking both Statement, I and II together:

Here, on merging both the statements we get the following diagram,

So, by combining both the statements, we can say J sits 3rd to the left of N, who visited W..

Clearly, Statement I and Statement II together are necessary to answer the question.

Hence, option E is the correct answer.
 

From statement I alone, we don’t get the answer.

From statement II alone, Q is sitting 2nd to the left of T. T is facing P. The number of friends sitting between P and Q is same as the number of friends sitting between P and W.

From statement II alone, we don’t get the answer.

Combining both statement I and II, we get,

From statements I and II together, we don’t get the answer.

Hence, option ‘D’ is correct.

Checking Statement I:

Using the above references, we get the following arrangement:

Clearly, W is sitting at the right end.

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

Checking Statement II:

Using the above references, we get the following different arrangement:

Thus we cannot find the final conclusion.

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

Hence, Option A is correct.
 

Checking → statement I:

References:

Point A is 3km north of library.

Point C is 3km North of Point B.

Point D is 3km East of point C.

Inferences:

From the above references, we can conclude that instruction about college is missing in statement I.

So, we can’t determine the direction between library and college.

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

Checking → Statement II:

References:

College is 7km North of point F.

Point D is 6km North of point E.

Library is 7km west of point E.

Point F is 4km East of point E.

Inferences:

From the above references, we can conclude the following.

We can conclude that library is to the South West direction with respect to college.

Thus, statement II alone is sufficient to answer the question.

Hence, option B is correct.

Checking → statement I:

References:

P is married to U.

V is married to R.

Q is the husband of W.

S is the daughter-in-law of W.

Inferences:

From the above references, we can conclude the following:

So, we can’t conclude the relation between X and S.

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

Checking → statement II

References:

V is the father of Q.

U is the mother-in-law of Q.

T is the sibling of X.

T is unmarried.

Inferences:

From the above reference, we can conclude the following:

So, we can’t conclude the relation between X and S.

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

Thus, statement I and II together is sufficient to answer the question.

Hence, option D is correct.

From Statement I:

From this statement, we get the following ranking.

Person in the row = 8 persons + Akansha + 4 persons + Rhea + 7 persons + Harshita + 8 persons

So, we get that Rhea is 17th from the bottom in the class.

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

From Statement II:

From this statement, we get the following ranking.

Person in the row = 11 persons + Yamini + 13 persons + Rhea + 4 persons

So, we get that Rhea is 5th from the bottom in the class.

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

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

Hence, option C is the correct answer.

From Statement I: From this statement, we get the following arrangement:

So, we get that X is 2nd to the left of Y.
