➪ Weight of 56 books = 8kg

$\small\mathbf\orange{{Using \: Unitary \: Method : }}$

$➪ \: 1kg = \frac{56}{8} = 7 \: books$

➪ Therefore, Weight of one book,

$➪ \: \frac{8}{56} = \frac{1}{7} \: kg$

➪ So, Weight of 154 such books,

$➪ \: \frac{154}{7} = 22kg$

And,

Number of books in 5 kg,

$➪ \: 5 \times 7 = 35 \: books$

Hence, There are 35 books weighing 5kg.
