Logical Reasoning(SBI-PO) Data Sufficiency

Direction (): In the following question, a given question is followed by information in three statements. You have to decide the data in which statement(s) is sufficient to answer the question and mark your answer accordingly.

A, B, C, D, E and F are six employees. Each of them gets different number of mails–15,20,30, 50, 60 and 70 everyday but not necessarily in the same order. Who is the shortest among all and what is the number of mails that D gets?

I. E is taller than only D and F. C is the tallest among all but does not get the least number of mails. A gets half the number of mails of what B gets.

II. A is taller than B. The sum of mails of A and E is equal to the number of mails that D gets. The one, who gets 50 mails is not the shortest. D does not get the highest number of mails.

III. A does not get 15 mails. B is not taller than A. D gets more mails than E but less than C.

Statement I and II together are sufficient.

Statement I alone or statement II alone is sufficient.

Statement II alone is sufficient.

Statement I and II together are not sufficient.

Statement I alone is sufficient.

Explanation:

Six employees: A, B, C, D, E and F. Different number of mails: 15, 20, 30, 50, 60 and 70.

From statement I: E is taller than only D and F. C is the tallest among all but does not get lowest number of mails. A gets half number of mails than that of B gets. From the given information, C () >_() >_() > E() > D/F() > F/D() So, either F or D is the shortest. So, statement I alone is not sufficient.

From statement II: A is taller than B. The sum of mails of A and E is equal to the number of mails that D gets. The one, who gets 50 mails is not the shortest. D does not get the highest number of mails. From the given information, A and E get (20) and (50) mails but not necessarily in same order. Also, D gets (70) mails every day. We cannot determine who among the following is the shortest. So, statement II alone is not sufficient.

From statement III:
A does not get 15 mails. B is not taller than A. D gets more mails that that of E but less than C.
From the given information, We cannot determine who among the following is the shortest. So, statement III alone is not sufficient.

On combining I and II:
We get, C(70) > A(30) > B(60) > E(20) > D(50) > F(15)
So, F is the shortest and D gets 50 mails every day.
Therefore, statement I and II together are sufficient.

On combining I and III:
We get, C() > A(30) > B(60) > E() > F/D() > D/F()
So, either F or D is the shortest.
Therefore, statement I and III together are not sufficient.

On combining II and III:
We cannot determine, who is the shortest. Therefore, statement II and III together are not sufficient

Hence, the data in statement I and II together are required to answer the question.
