Given that we have seven books P, Q, R, S, T, U, and V.

Basically, this question is based on its cover's color, its condition, and its type. We can proceed step by step using the tabular form.

Statement 2: Based on the condition of books, i.e., Only S and U are new books and the rest are old.

M12

Statement 3: Based on the type of books, i.e., P, R, and S are law reports; the rest are Gazetteers.
