Explanation:

Let the cost price of each bottle be Rs. x.
Cost price of both the bottles = Rs. 2x
Selling price of both the bottles = 2x × 110% = Rs. 2.2x
Selling price of the first bottle = 125% of x = Rs. 1.25x
Selling price of the second bottle = Rs. (1.25x – 2160)
According to the data provided in the question, we get:
1.25x + 1.25x – 2160 = 2.2x
⇒ 2.5x – 2.2x = 2160
⇒ x = 7200
Cost price of the each bottle = Rs. 7200
