If a set of 56 books weighs 8000 grams, you can get average weight of a book, which is
8000
56
=
142.86
grams.
Now you can compute weights of 152 books
=
152
⋅
142.86
=
21715
grams or approximately 21.7 kg.
If you want to buy 5 kg book, you need to get
5000
142.85
=
35
books. In other words, 35 books weigh 5 kg (or 5000 grams).
