35 books weigh 5kg

Answer 2

Answer:

Weight of 154 such books = 21.99 kg

Number of books that weigh together 5 kg = 35

Step-by-step explanation:

Let the weight of 1 book be x

Weight of 56 books = 8 kg = 8000 g = 56x

8000 g = 56 x

x = 8000/56

x =  142.8 g

Weight of 154 books = 154x = 154(142.8) = 21991.2 g = 21.99 kg

Let the number of books be y.

142.8y = 5000

y = 5000/142.8

y = 35

Number of books that weigh together 5 kg = 35

Hence,

Weight of 154 such books = 21.99 kg

Number of books that weigh together 5 kg = 35
