Chapter 3. Data Sufficiency Reasoning

Directions for data sufficiency questions (1-10):

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

B. If data in the statement II alone is sufficient to answer the question.

C. If data either in the statement I alone or statement II alone are sufficient to answer the question.

D. If data given in both I & II together are not sufficient to answer the question.

E. If data in both statements I & II together are necessary to answer  the question.

( Explain A / B if statement I/II is true, C any one correct, D both are not correct, E if statement I and II both are require to complete the ans)

Question 1. Who is taller among P, Q, R, S & T?

I. S is shorter than Q. P is shorter than only T.

II. Q is taller than only S. T is taller than P and R.

Answer : (C)

Explanation:

From I : P is shorter than only T, this means that P is taller than all Q, R & S, so T is tallest.

From II : Q only taller than S, so S is shortest, and Q is second shortest, Now T taller than P and R both, So tallest of all.

Question 2. What is the distance between point P and point Q?

I. Point R is 10 m west of point P and point S is 10 m north of point P.

II. Point Q is 10 m south-east of point R. Point S is 20 m north-west of point Q.

Answer : (D)

Explanation:

From I : No relation between points P and Q

From II : In this since we don’t know the angles between sides of triangle forming with points PQS and PQR, PQ cannot be determined.

Question 3. How is Shubham related to Shivani?

I. Shubham is brother of Meenal. Shivani is niece of Pooja.

II. Neeraj is Meenal’s uncle and Preeti’s brother

Answer : (D)

Explanation:

Either statement cant give the answer.

From both statements we can get the relationship as Pooja is Neeraj’s sister but it cannot be clearly said that Shubham & Meenal are Pooja’s children or not & Shivani is Neeraj’s daughter, because there can be other siblings of Neeraj and Pooja also.

Question 4. How is PRODUCT written in that code language?
I. In a certain code language, AIEEE is written as BJFFF.

II. In a certain code language, GYPSY is written as FXORX

Answer : (E)

Explanation:

From I: All vowels are coded as next alphabets

From II: All consonants are coded as previous alphabets

So from both the statements.

Question 5. How is ‘face’ written in that code language?

I. In a certain code language, ‘no one with face’ is coded as ‘fo to om sop’ and ‘no one has face’ is coded as ‘om sit fo sop’

II. In a certain code language, ‘face of no light’ is coded as ‘om mot fo kiz’ and ‘no one is smart’ is coded as ‘sop fo sip lik’.

Answer : (E)

Explanation:

From I : ‘no one face’ is coded as ‘om fo sop’

From II : ‘no’ is ‘fo’

Now from both – ‘one face’ is ‘om sop’ and now from II: ‘face of no light’ is written as ‘om mot fo kiz’, ‘face’ is ‘om’

Chapter 4. Inqualities

Direction: (1-5): In these question, @, #, $, * & % symbols are used for different meaning as follows:

‘A @ B’ means A is not less than B.

‘A # B’ means A is neither less than nor equal to B.

‘A $ B’ means A is neither less than nor greater than B.

‘A * B’ means A is not greater than B.

‘A % B’ means A is neither greater than nor equal to B.

Considering all the statement in each question true, find that which of the following two conclusion – I & II is definitely true.

Give the answer (A) if only conclusion I is true.

Give the answer (B) if only conclusion II is true.

Give the answer (C) if either conclusion I or conclusion II is true.

Give the answer (D) if neither conclusion I nor conclusion II is true.

Give the answer (E) if conclusion I & conclusion II – both are true.

Q4 – E

Q5 - D

===========================

Explanation/Solution -:

From the given clues there are five persons with four different professions living in four

different cities owning four different cars. They all have different height. Following table can

be made, in which rank 1 is given to the tallest and 5 to the shortest:

Since, the engineer lives in Pune and owns a city, he must be Rohan. Further, a Chartered

Accountant and a doctor (eye specialist) owns a superb implies Prachi is the Chartered

Accountant and Sarthak owns Innova, Gagan is an Architect and Kanika lives in Mumbai. As

Prachi is the Chartered Accountant, she is the tallest and the eye specialist lies between

Chartered Accountant and Engineer height-wise implies rank in terms of height of Eye

specialist and Engineer is 2 and 3 respectively. Therefore, rank of Gagan, the architect is 4.

Following is the final table:
