hey mate ,here is your answer
Step-by-step explanation:
→ Unitary method

→ 1 book will weigh= 8/56 kg's
→ So 152 such books will weigh= 8/56 x 152
→ =21.714 kg 's
→ Now, we have been asked how many such books will weigh up to 5 kg....
→ If 8 kg weight is of 56 books
→ Then 1 kg will be the weight of 56/8 books
→ And 5 kg will be the weight of 56/8 x 5 books
→ i.e., 7x5= 35 books
→ Hence 35 books will weigh up to 5 kg
