Verbal Reasoning - Data Sufficiency - Discussion

In each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and

Give answer

  • (A) If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question
  • (B) If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
  • (C) If the data either in statement I alone or in statement II alone are sufficient to answer the question
  • (D) If the data given in both statements I and II together are not sufficient to answer the question and
  • (E) If the data in both statements I and II together are necessary to answer the question.

Question: Among A, B, C, D, E and F, who is the heaviest ?

Statements:

  1. A and D are heavier than B, E and F but none of them is the heaviest.
  2. A is heavier than D but lighter than C.

[A]. I alone is sufficient while II alone is not sufficient
[B]. II alone is sufficient while I alone is not sufficient
[C]. Either I or II is sufficient
[D]. Neither I nor II is sufficient
[E]. Both I and II are sufficient

Answer: Option A

Explanation:

From I, we conclude that since none of A and D is the heaviest and each one of B, E and F is lighter than both A and D, so C is the heaviest.

According to Statement 1, "C" can either be the heaviest or the lightest, we can't conclude whether "A", "D" or "C"is the heaviest, so the information of Statement 1 is not sufficient enough. But with the details provided in Statement 2, "C" is heavier than "A" and "D", therefore, I think the answer should be [E], not [A].

I thought you were right at initially, but not actually.

Let me explain.

Split the first statement as given below:
a. A and D are heavier than B, E and F
b. but none of them is the heaviest.

From a, A & D are heavier than B, E, F. So we can ignore B, E, F. Now remaining are A,D and C.

From b(none of them heaviest), denotes that either A or D is not heaviest.

Now, only C left. Therefore C is heaviest.

Hence, "I alone is sufficient while II alone is not sufficient" is the correct answer.

@Sundar here you are using the 2nd statement for the answer so, how the correct option is A.

The answer should be E.

@Sat120 b. Is not the second statement, its just second half of first statement.
