Problem Analysis

To solve this problem, we need to calculate the final price of the gloves after the price increase in autumn and the price decrease in winter. The initial price of the gloves is given as 200 rubles. In autumn, the price increased by 20%, and in winter, it decreased by 10%. We need to find the final price of the gloves after these changes.

Solution

Let's calculate the price changes step by step:

1. Autumn price increase: The price increased by 20%. To calculate the new price, we can multiply the initial price by 1.2 (100% + 20% = 120%).

New price after autumn increase = 200 * 1.2 = 240 rubles. 2. Winter price decrease: The price decreased by 10%. To calculate the final price, we can multiply the price after the autumn increase by 0.9 (100% - 10% = 90%).

Final price after winter decrease = 240 * 0.9 = 216 rubles. Therefore, the final price of the gloves is 216 rubles after the price increase in autumn and the price decrease in winter.
