Answer 1

⭐Question:-

                      Q)  cost of 5 book 125 what os the cost of 6 book

⭐Answer:-

So,

   5 copies cost Rs. 125, So cost of dozen copies?

    So before I show you the solution remember that  

$1 Dozen = 12$

So we should find the cost of 12 copies.

So, If

Copies                     Cost

$5$                                $125$

$12$                              $x$

Now cross multiply,

$=5*x\\\\=125*125x\\\\= 1500\\x\\\\= 1500/5x\\\\= 300$

So the cost of 12 copies is Rs. 300
