Answer 2

Answer:

Cost of 400 copies =1800 Rupees

Step-by-step explanation:

According to the information provided in the question it is given as

120 copies of a book cost= Rupees 540

We need to find what will 400 copies of the costs

For solving the question we make a simple equation as follows

Let us assume x is the cost of 400 copies

120 = 540

400= x

By simple cross multiplication we get the value of x

[tex]120 x =540\times 400\\ 120x = 216000\\ x= \frac{216000}{120} [/tex]

Reducing or cutting zeros

$x= \frac{21600}{12}$

$x= 1800 Rupees$

Hence cost of 400 copies =1800 Rupees
