$\bold{Explanation:}$

Given:

The weight of 100 notebooks is 50 kg

To Find :

Weight of 150 such notebooks and ratio of two weights

100 Notebooks weight = 50 kg

150 Notebooks weight =?

Concept :

Divide the Weight of notebooks of less quantity with the notebooks having more quantity and then multiply it with weight which is given.

$\sf = > \dfrac{150}{100} \times 50$

$\sf = > \dfrac{15}{10} \times 50$

$\sf= > 15 \times 5 = 75 \: kg$

$\therefore$ The weight of 150 such notebooks is 75 kg

Now , finding ratio of weights.

$\sf = > \dfrac{75}{50} = \dfrac{15}{10} = \dfrac{3}{2}$

$\huge \bold{Ratio\: is \:3:2 }$
