Answer 2

Problem Analysis

Roma and Petya collected apples and decided to sell them. Each of them has 120 apples. Petya sells 5 apples for 15 rubles, while Roma divided the apples into large and small ones and sells them at different prices: 8 rubles for a pair of large apples and the same price for three regular ones. Roma has 66 large apples. We need to determine who will earn more and by how much.

Solution

To solve this problem, we need to calculate the earnings of Petya and Roma and compare them.

Calculation

Let's start by calculating Petya's earnings. Petya sells 5 apples for 15 rubles. Since he has 120 apples, he can make 120 / 5 = 24 sets of 5 apples. Therefore, Petya's earnings are 24 * 15 = 360 rubles.

Now let's calculate Roma's earnings. Roma has 66 large apples. He sells a pair of large apples for 8 rubles, so he can make 66 / 2 = 33 pairs. Therefore, Roma earns 33 * 8 = 264 rubles from selling large apples.

Roma also sells regular apples. Since he has 120 apples in total and 66 of them are large, he has 120 - 66 = 54 regular apples. Roma sells three regular apples for the same price as a pair of large apples, which is 8 rubles. Therefore, he can make 54 / 3 = 18 sets of three regular apples. Therefore, Roma earns an additional 18 * 8 = 144 rubles from selling regular apples.

Adding up Roma's earnings from selling large and regular apples, we get 264 + 144 = 408 rubles.

Conclusion

Petya earns 360 rubles from selling apples, while Roma earns 408 rubles. Therefore, Roma earns more than Petya by 408 - 360 = 48 rubles.

Roma will earn more than Petya by 48 rubles.
