Calculation of the Initial Price of Apples

To calculate the initial price of apples, we need to consider that the price first increased by 60% and then decreased by 20%. Let's assume the initial price of apples was x rubles.

1. The price of apples increased by 60%, which can be expressed as 1.6x. 2. The price of apples then decreased by 20%, which can be expressed as 0.8(1.6x).

According to the information provided, the final price of apples after the decrease is 240 rubles. We can set up the equation:

0.8(1.6x) = 240

To find the initial price of apples, we can solve this equation:

0.8 * 1.6x = 240

0.8 * 1.6x = 240

1.28x = 240

x = 240 / 1.28

x ≈ 187.5

Therefore, the initial price of apples was approximately 187.5 rubles.

Please note that the above calculation assumes a linear relationship between the percentage changes in price. In reality, the relationship may be more complex, and additional factors could affect the price fluctuations.
