Answer 2

Answer:

(i) Weight of 154 books = 22 kg.

And

(ii) 5 kg is weight of 35 books.

Step-by-step explanation:

Given,

Weight of 56 books = 8 kg

According to the question

(i)

Weight of 56 books = 8 kg

Weight of 1 book = 8/56 kg

Weight of 154 books = 8/56 × 154 kg

Weight of 154 books = (8 × 154)/56 kg

Weight of 154 books = 1232 / 56 kg

Weight of 154 books = 22 kg

(ii)

8 kg is the weight of 56 books

1 kg is the weight of 56/8 books

1 kg is the weight of 7 books

5 kg is weight of 5 × 7 books

5 kg is weight of 35 books.

Hence,

(i) Weight of 154 books = 22 kg.

And

(ii) 5 kg is weight of 35 books.
