Arrangement sets in the DILR section often involve arranging given data or elements in a specific order based on certain criteria or conditions. These sets can include:

  1. Seating Arrangement: Questions where individuals or objects are arranged in a specific order around a table or in a row based on given conditions or relationships.

  2. Sorting/Ordering Problems: Problems where items need to be arranged in a particular sequence based on certain parameters or rules.

There are 12 volumes (books) of an Encyclopedia i.e. A to L. These are kept on a shelf in two rows – row 1 and row 2 such that row 1 is directly above row 2. All the books have identical dimensions and are at equal distances from their neighbours. There are six books in each row, and each book in row 2 has one book directly above it in row 1. There are no other books on this shelf. Further:

The distance between books F and L is the same as the distance between books G and D. This distance is more than the distance between any two books on the shelf.

Books A, D and E are in row 1. Books H, I and J are in row 2.

There is exactly one book to the left of book B.

Book A is equidistant from books J and H. Book E is equidistant from books I and L.
