Data Sufficiency

Q: In a certain code language, what is the exact code for the word 'flies'? (Assume codes are randomly assigned to words) I. 'flies time' is coded as 'delta...

Correct Answer: Option C (Both statements I and II together are necessary.). From Statement I: 'flies' could be 'delta' or 'epsilon'. Not sufficient. From Statement II: Deals with 'time' and 'it'. Not sufficient. Combining I and II: The common word is 'time' and the common code is 'epsilon'. Therefore, 'time' = 'epsilon'. This leaves 'flies' = 'delta' in the first statement. Both statements are necessary.

Q: How is Qadir related to Mona? I. Nitin, the brother of Mona, is the only son of Pooj

Correct Answer: Option B (Statement II alone is sufficient.). From Statement I: There is no mention of Qadir. Not sufficient. From Statement II: Qadir is clearly stated as the mother of Nitin and Mona. Thus, Qadir is the mother of Mona. Statement II alone is sufficient.

Q: In a certain code language, what is the code for 'pays'? (Assume the codes are randomly assigned to words) I. 'pays always hard' is coded as 'zeta epsilo...

Correct Answer: Option A (Statement I alone is sufficient.). From Statement I: Comparing both sentences, 'always hard' corresponds to 'epsilon delta'. The unique word left in the first sentence is 'pays', and its unique code is 'zeta'. Sufficient. From Statement II: There is no information regarding 'pays'. Not sufficient. Statement I alone is sufficient.

Q: On which day of the week did Xavier visit the bank? (Assume the week starts on Monday). I. Xavier visited the bank after Wednesday but before Saturday, and it was not on Thursday....

Correct Answer: Option A (Statement I alone is sufficient.). From Statement I: The days between Wednesday and Saturday are Thursday and Friday. Since the visit was not on Thursday, it must be on Friday. Statement I alone is sufficient. Statement II gives a wide range.

Q: Six persons are sitting in two parallel rows containing three people each, facing each other. Is Aman facing Deepa? I. Aman sits at one of the extreme ends of the North-facing row...

Correct Answer: Option D (Both statements I and II together are not sufficient.). From Statement I: We know the positions of Aman, Charu, and Bikas, but not Deepa. From Statement II: Deepa is at an extreme end next to Bikas. Combining I and II: Since Bikas is in the middle of the South-facing row, Deepa could be at either the left extreme or the right extreme of that row. Therefore, Deepa might be facing Aman or the other person. Both statements together are not sufficient.
