Answer 2

Given:

120 copies of a book cost are 600 Rs.

To find:

The cost of 400 copies.

Solution:

The cost of 400 copies is 2,000 Rs.

To answer this question, we will follow the following steps:

First of all, we will find the cost of one copy and then the cost of 400 copies.

Now,

As given in the question, we have,

The cost of 120 copies = 600 Rs.

So,

The cost of 1 copy

$= \frac{600}{120}$

$= 5 \: rs.$

Now,

The cost of 400 copies

$= \: cost \: of \: 1 \: copy \: \times 400$

$= 5 \times 400$

$= 2000 \: rs.$

Hence, the cost of 400 copies is 2000 Rs.
