Answer :

Certainly! Let's solve the problem step by step.

1. Calculate the price per dozen:
- We know that 5 dozen copies cost Rs. 7200.
- To find out the cost of one dozen (12 copies), we can divide the total cost by the number of dozens.
[tex]\[ \text{Price per dozen} = \frac{7200}{5} = 1440 \text{ Rs.} \][/tex]

2. Calculate the price per copy:
- Now that we know the price of one dozen is Rs. 1440, we need to determine the price of a single copy.
- Since one dozen is 12 copies, we divide the price per dozen by 12.
[tex]\[ \text{Price per copy} = \frac{1440}{12} = 120 \text{ Rs.} \][/tex]

3. Calculate the number of copies that can be bought for Rs. 2280:
- We are given that we have Rs. 2280 and we want to find out how many copies we can buy with this amount.
- We simply divide the total amount by the price of one copy.
[tex]\[ \text{Number of copies} = \frac{2280}{120} = 19 \][/tex]

Therefore, with Rs. 2280, we can buy 19 copies.
