I will be glad to assist you, let's start-

The total no. of copies being bought for 300 = 5 copies
Therefore no. of copies can be purchased 
for 1 = 5/300 = 1/60 copies
Therefore no. of copies can be purchased for 1500 = 1/60*1500 = 25 copies
And that's the answer.

Cost of 5 copies = 300 Rs.

Let x be the components of numbers of copies and y be the respective cost.

 x_{1} = 5 , y_{1} = 300
 x_{2} = ? , y_{2} = 1500

We know that Here x and y are in direct proportion as cost increases with number

x1/x2 = y1/y2

5/x2 = 300/1500

5/x2 = 1/5

x2 = 25 .

Therefore, 25 books or copies can be bought for 1500 Rs.
