Answer:

Option (a) is correct

Step-by-step explanation:

Given;

Weight of 8 books= 5 kg.

Weight of 1 book= weight of 8 books/no. of books

                            = 5/8

Weight of 12 books=weight of 1 book× no. of books

                               = (5/8)×12

                               = (5×3)/2

                               =15/2=7.5 kg
