56 books weigh 8kg
1 book will weigh 8/56kg
So, 154 books will weigh (8*154)/56 = 22kg
Now,
8kg is weighed by 56 books
1kg will weigh by 56/8 books
So, 5kg will be weighed by (56*5)/8 = 35 books
Hope the answer is correct............

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).
