Data Sufficiency - Base Level 1
Practice and master this topic with our carefully crafted questions.
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.
As given in I and II, R studies in school D and J studies in school F. So, T does not study in school D or school F. Thus, T studies in any one of the schools B, C or E.
From I, we conclude that H is the only daughter of M. But this does not indicate that M has no son. The information given in II is immaterial.
From I, we conclude that Sulekha is the wife of Nandini's mother's only son i.e. Nandini's brother. Thus, Sulekha is Nandini's sister-in-law. From II, we conclude that Sulekha is the cousin of Nandini's husband, which implies that Sulekha is Nandini's sister-in-law.
From I, we have : R > Q, R > T, S > R i.e. S > R > Q > T or S > R > T > Q. From II, S is not the heaviest. So, P is the heaviest. Thus, we have : P > S > R > Q > T or P > S > R > T > Q Hence, either T or Q is the lightest.
In I and II, the common codes are '5', '#' and '3' and the common words are 'flowers', 'are' and 'good'. Thus, in I, the remaining code '$' stands for 'really'.
As given, we have : M > K, A > S. From II, K > A. Thus, we have : M > K > A > S. So, Sharad is the youngest. From I, M > S. Thus, we have : M > K > A > S or M > A > K > S or M > A >S > k
From I and II we conclude that A is either son or daughter of D.
In I and II, the common word are 'me' and 'water' and the common code numbers are '7' and '1'. So, the code for 'water' is either '7' or '1'.
From I, we conclude that Divya's mother is Shaloo's aunt or Divya is Shaloo's cousin. Now Divya's grandfather's only child is Divya's parent. So, from II, we conclude that Shaloo and Divya are daughters of the same parent i.e. Divya is Shaloo's sister.
From I and II, we conclude that Anjali was born in February 2004 on a date which is an even prime number. Since the only even prime number is 2, so Anjalli was born in February, 2004.
