Data Sufficiency Questions and Answers

Answer: D

Correct answer: Both 1 and 2 are sufficient

Statement 2 gives Sunday’s sales: every third of 1500 visitors bought a box, so 500 were sold. Statement 1 makes Monday ten per cent more, that is 550. Neither works alone - the first is a ratio without a base and the second gives only Sunday.

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'.

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: 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: D

In 'You eat many mangoes' and 'Who others eat bananas', the common word is 'eat' and the common code word is 'Le'. So, 'Le' means 'eat'.

In 'You eat many mangoes' and 'They eat bananas and mangoes', the common code word 'Le' stands for 'eat'. So, the other common code word 'Na' stands for the other common word i.e. 'mangoes'.

Answer: D

From 1, we have the order: B, E, D.

From 2, B is at the extreme left of the row.

Thus, considering both 1 and 2, we conclude that among the five children, D is the third and hence the middle child in the row.

Answer: A

From 1, we have: number of employees who opted for VRS = 18% of 950 + 6% of 1100 = 171 + 66 = 237.

From 2, we cannot get the required answer until and unless the number of employees in age-group 51 to 56 and other age-groups is known.

Answer: D

From 1, we have: N > M, N > P, D > N. Thus, we have: D > N > M > P or D>N> P>M.

But, from 2, M earns more than P i.e. D > N > M > P. Also, since P earns less than K and N earns less than only D, so we have: D>N>K>M>P or D>N>M> K > P.

Hence, either K or M earns more than only the least earner i.e. P.

Answer: C

From 1, We know that in a class of 25 students, Amit ranks 18th from the bottom and 8th from the top.

Sachin is three ranks above Amit and so, Sachin ranks 5th from the top.

From 2, Deepti ranks 23rd from the bottom and hence, 3rd from the top. Sachin, being 2 ranks below Deepti, is, thus, 5th from the top.

Answer: D

Correct answer: Both 1 and 2 are sufficient

Statement 2 says a bus left fifteen minutes ago, that is at 7.45. Statement 1 gives a thirty minute interval, so the next leaves at 8.15. Statement 1 alone gives the interval without a reference departure, and statement 2 alone gives a departure without the interval, so both are needed.
