Answer 2

Calculation of the Discount Percentage

To calculate the discount percentage, we need to find the difference between the original price and the discounted price, and then divide that difference by the original price.

In this case, the original price of the juice is 70 rubles, and the pensioner paid 65 rubles and 10 kopeks.

The difference between the original price and the discounted price is 70 rubles - 65 rubles - 10 kopeks = 4 rubles and 90 kopeks.

To calculate the discount percentage, we divide the difference by the original price and multiply by 100:

(4 rubles and 90 kopeks / 70 rubles) * 100 = 6.8571%

Therefore, the discount percentage for the juice is approximately 6.86%.
