Data Sufficiency Questions and Answers

Answer: D

In the given statement and 1, the common word is 'They' and the common code word is 'nop'. So, 'nop' is the code for 'They'.

In the given statement and 2, 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'.

Answer: C

From 1, we conclude that 5th, 12th, 19th and 26th of March, 2006 were Sundays.

So, the last Sunday fell on 26th.

From 2, we conclude that 31st March, 2006 was Friday. Thus, 26th March, 2006 was the last Sunday of the month.

Answer: D

Correct answer: Neither 1 or 2 is sufficient

Statement 2 places Rajan twentieth from the left and statement 1 puts ten children between him and Sumit, which fixes Sumit’s position from the left as either ninth or thirty-first. But the total number of children in the row is never given, so the position from the right cannot be computed at all.

Answer: B

Correct answer: 2 alone is sufficient while 1 alone is not sufficient

The stem gives Madan above Kamal and Arvind above Sharad. Statement 2 adds Kamal above Arvind, completing the chain Madan, Kamal, Arvind, Sharad and making Sharad the youngest. Statement 1 places Sharad below Madan, which was already implied by nothing and still leaves Sharad and Kamal unordered.

Answer: D

Correct answer: Both 1 and 2 are sufficient

Statement 1 puts D above A and C; statement 2 puts E above B above D. Joined at D the order is E, B, D, then A and C, so E is the tallest. Statement 1 alone says nothing about B and E, and statement 2 alone says nothing about A and C, so neither can identify the tallest by itself.

Answer: C

Correct answer: Either 1 or 2 is sufficient

From statement 1, R third to the left of Q and P second to the right of R gives the order R, P, S, Q, T reading left to right, so S is immediately right of P. From statement 2, T second to the right of P with Q immediately left of T gives R, P, Q, T with S filling the remaining place - and again S sits immediately right of P. Each alone fixes the arrangement.

Answer: D

To find the code for 'we', we need to have any of the following:

(i) 'We are friends' should have only 'We' common with another statement, as in 2;

(ii) 'We are friends' should have only 'are' and 'friends' common with another single or two statements, as in 1 and 3. Thus, we need Either 2 only or 1 and 3 only

Answer: D

Correct answer: Neither 1 or 2 is sufficient

Each statement gives a string of digits for a phrase, but nothing indicates which digit corresponds to which word - the codes are not aligned with the words in order. The two phrases share ‘water’ and ‘me’, and their code strings share more than one digit, so even together the code for ‘water’ cannot be isolated.

Answer: C

Correct answer: Neither 1 nor 2 is sufficient

Statement 2 establishes that A and B are both D’s children and that B is a son, and statement 1 adds that there are three children in all. But the sexes of A and the third child are never given, so the number of sons may be one, two or three and cannot be determined.

Answer: C

In given statement and 1, the common words are 'tie' and 'clip' and the common codes are '2' and '9'. So, '2' and '9' are the codes for 'tie' and 'clip'. Thus, in the given statement, '7' means 'button'. In given statement and II, the common code word '7' represents the common word 'button'.
