Data Sufficiency Test Series 3, Data Sufficiency Question Answers

From I: J, P > K > M, T => Either J or P is the tallest.
Hence, statement I alone is not sufficient.
From II: P is not the tallest. Hence statement II alone is 81 not sufficient.
But, from I and II, it is obvious that J is the tallest among M, J, K, P and T.

From I: S P T R
From II: T R Q East
Combining I and II, we get, S P T R Q
Hence Q is at extreme right.

From I: P > R, P > T, U > P, U > Q, U > S
=> U is tallest. [Since U is taller than P, Q & S ans P is taller than R and T]
From II: __ R P — (2)
From (1) and (2) __ R P Q U Hence U is tallest.

From both the statements together, we conclude that the price of the new car is Rs(25000 * 3) i.e., 75000.
So, Ronnie had to pay Rs(75000 – 25000) = Rs.50000. Thus, both I and II are required.

From II: The 3rd, 6th, 9th, 12th, 15th, 18th, 21st, 24th and 27th positions are occupied by girls.
From I: Shridhar is 14th from the right.
Hence, using I & II, we can get the no. of boys required.

Comparing the information in the question with statement I, we find that ‘2’ and ‘9’ are the codes for ‘tie’ and ‘clip’. So, ‘7’ represents ‘button’. Thus, I alone is sufficient. Again, comparing the information in the question with II, we find that the common code number ‘7’ stands for common word ‘button’. Thus, II alone also is sufficient.

From the given statements, we find that:
K + T > S and R + K

In the given statement and I, the common word is ‘They’ and the common code word is ‘nop’. So, ‘nop’ is the code for ‘They’.
In the given statement and II, the common word is ‘like’ and the common code word is ‘al’. So ‘al’ is the code for ‘like’.
Thus, in the given statement, ‘ed’ is the code for ‘flowers’.

From I and II, we conclude that there are 16 students above Reena in rank. Thus, Reena’s rank is 17th in the class. So, both the statements are necessary.

From I, we have: A – [(A + 4000)/2] = 500 or A – 4000 = 1000 or A = 5000.
i.e., Atul’s monthly salary = Rs.5000.
From II, we have: (A + R)/2 = 4500 or A + 4000 = 9000 or A = 5000.
Thus, either I or II is sufficient.

From the both statements together, we find D is the father of B and B is the brother of A. So, D is the father of A. Thus, both the given statements are needed.

From I: R – PQ (Hence Q is immediate right of P).
From II: PQT (Hence Q is immediate right of P).

From I: B is either maternal uncle or maternal aunt of H.
Hence, statement I alone is not sufficient.
From II: B is father of T.
Statement II does not give any information about H.
Hence, statement II alone is also not sufficient. Statement I Jacks information regarding sex of B. In order to answer the question we need information regarding the sex of B. Statement II fulfills this need.
If B is father of T, it is obvious that B is a male.
Hence, from I and II, B is maternal uncle of H.

In I and II, the common codes are ‘nip’ and ‘sre’ and the common words are ‘is’ and ‘beautiful’. So ‘nip’ and ‘sre’ are the codes for ‘is’ and ‘beautiful’. But, the exact word for ‘nip’ cannot be found out.

The given statements can be represented in the basic diagram as follows.

Conclusion I, affirmative, does not follow.
Conclusion II, affirmative, follows.
Conclusion III, affirmative, does not follow.
Only II follows.

The basic diagram for the given statements is:

From the above basic diagram, conclusion I, affirmative, does not follow.
The possible diagram for conclusion II is,

From the above diagram, conclusion II follows.
Only II follows.

From I: S > T > P, Q
From II and using I: S > T > P, Q > R
Hence either P or Q ranks third in terms of salary.

I alone is not sufficient because the word ‘go’ is absent in statement I. Statement II alone is not sufficient because there is no such indication by which we can find out code for ‘go’. Note that you can’t assume that the codes used for words of the statement are in the same order as the words are.
Now when we use the data given in both statements we can get code for ‘may’ only, ie. ‘pic’.

From I: It means the sun is to the left of Shashidhar and since it is morning, the left of Shashidhar is East. Hence, Shashidhar is facing South.
From II: Sun is to the left of Shashidhar. Hence, he is facing South.[Since it is morning].

From both the given statements, we find that:
Praveen’s salary = 115% of (90% of Rs.2500) = Rs.2587.50.
So, both I and II are required.
