Question
Six books, F through K are placed one above another,
where the bottommost position is 1 and the position above it is 2 and so on. Which book is placed at the bottommost position? Statement I: H is placed second to the above of F, which is placed just above of K. One book is placed between G and J. I is placed below J. Statement II: Two books are placed between G and F. One book is placed between H and F. The question given below consists of 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 all the statements and give answer.Solution
From I. From I.
I is placed at the bottommost position. So, statement I alone is sufficient. From statement II alone, insufficient information is given. So, statement II alone is not sufficient.
