Answer 2

Answer:

If a set of 56 books weighs 8000 grams, you can get average weight of a book, which is

$\frac{8000}{56} = 142.86 \: grams$

Now you can compute weights of 152 books

$152 \times 142.86 \: = 21715 \: grams$

If you want to buy 6 kg book, you need to get

$\frac{6000}{142.86} = 41 \: books$

your answer is 41 books
