Given :-

Weight of 144 books(one gross) = 18 kg

To Find :-

Weight of 24 such books

Solution :-

We know that,

$\large{\boxed{\green{\sf{1 \: kg = 1000 \: gm}}}}$

So,

Weight of 1 book = 18000/144

Weight of 1 book = 125 gm

Now,

Weight of 24 books will be = 125 * 24

Weight of 24 such books will be = 3000 gm

So, option 2 is correct
