|
Answer is: DFrom statement 1,
L is the husband of D. As L has three children, D also has three children.
From statement 2,
N, S, and P are siblings and are the children of L and of D also. Thus D is the mother of S.
5. | Statement: Among five friends J, K, L, M and N each of a different height, who is the second tallest?
1. N is taller than M and K. K is shorter than M.
2. L is taller than N. J is not the tallest. | | (a)The data is neither in statement 1 nor in statement 2 are sufficient to answer the question. | | (b)The data is in statement 1 alone are sufficient to answer the question, while The data is in statement 2 alone are not sufficient to answer the question. | | (c)The data either in statement 1 alone or in statement 2 alone are sufficient to answer the question. | | (d)The data in both the statement 1 and 2 together are necessary to answer the question. |
|
Answer is: AFrom statement 1,
N > M > K
From statement 2,
L > N
From both the statements,
L > N > M > K
but height of j is not clear. thus second tallest friend cannot be determined. Hence, data neither in statement 1 nor in statement 2 are sufficient to answer the question.
6. | Statement: How many students are there in the class?
1. There are more than 20 but less that 27 students in the class.

|
Answer is: BFrom statement 1,
Number of students in the class = 21 or 22 or 23 or 24 or 25 or 26
From statement 2,
Number of students in class = 25 or 26 or 27 or 28 or 29 or 30
Since, number of students can be divided into groups of 5 students, therefore number of students must be a multiple of 5.
so, number of students in the class = 25 or 30
Combing statement 1 and 2.
number of students in the class = 25
Hence, the data in both the statements 1 and 2 together are necessary to answer the question.

|
Answer is: CFrom statement 1,
R A _ G E
Clearly, the left place or empty place filled by N.
From statement 2,
_ A N G _
_G N A _
Clearly, N is at third place.
Hence, the data either in statement 1 alone or in statement 2 alone are sufficient to answer the question.
