A student entrepreneur started a company that manufactures sanitizers in two sizes – small and large.
The cost of a small bottle of sanitizer is \(₹10\) and that of a large bottle is \(₹14\). In June, the company sold \(1300\) bottles and recorded a total sale of \(₹15200\). Seeing the increased demand, the company decided to increase the price of both sanitizer bottles by \(₹2\) each. In the next month, the company sold \(1900\) bottles and recorded a total sale of \(₹26400\). Based on the above information,calculate an answer the following questions:
(i) Form a linear equation in two variables representing the sale for June.
(ii) Form a linear equation in two variables representing the sale for July.
(iii) How many sanitizer bottles of each type were actually sold in June?
(iv) How many sanitizer bottles of each type were sold in July?
