Step-by-step explanation:

According to the information provided in the question.

It is stated in the preceding question that,

The presented information is Rupa bought 15 books,

Cost price of each book is Rs.375

Selling price of each book is Rs.485

We need to find the gained selling on the books.

So, the cost of 15 book is as follow,

$C.P=15\times 375\\C.P=Rs.5625$

Now, the selling price of 15 book is as bellow,

$S.P=15\times 485\\S.P=Rs.7275$

Therefore the gain by selling 15 book will be,

$Gain=S.P-C.P\\Gain=7275-5625\\Gain=Rs.1650$
