c) Either I or II is sufficient
d) Both I and II are sufficient

Explanation: From I, we have the order: B, E, D.
From II, B is at the extreme left of the row.
Thus, considering both I and II, we conclude that among the five children, D is the third and hence the middle child in the row.

6. Question : How is R related to M ?

Statements :
I. M's brother is husband of P.
II. P is mother of R's sister.
a) I alone is sufficient while II alone is not sufficient
b) II alone is sufficient while I alone is not sufficient

From I, B is the daughter of M. So, M is either father or mother of B.
Clearly, the correct relationship between M and N cannot be deduced.

8. Question : How many girls are taller than Shravan in his class ?

Statements :
I. When students of Shravan's class are ranked in descending order of their heights, Shravan's rank is 17th from the top among all the students and 12th among boys.
