Answer 3

Solution:

To solve this problem, we can set up a system of equations based on the given information and then solve for the unknown quantities.

Let's denote: - x as the cost of 1 kg of apples in rubles, - 2x as the cost of 1 kg of apricots in rubles.

Given: - 5 kg of apples and 5 kg of apricots were bought for 600 rubles. - The cost of apricots is 2 times the cost of apples.

We can express this information in the following equations:

1. 5x + 5(2x) = 600 (Total cost of apples and apricots is 600 rubles) 2. 5x + 10x = 600 3. 15x = 600 4. x = 40

So, the cost of 1 kg of apples is 40 rubles, and the cost of 1 kg of apricots is 80 rubles.

Now, we can use this information to find out how many kilograms of apricots can be bought for 240 rubles.

Let's denote: - y as the number of kilograms of apricots that can be bought for 240 rubles.

We can express this information in the following equation:

5 * 40 + y * 80 = 240 200 + 80y = 240 80y = 240 - 200 80y = 40 y = 40 / 80 y = 0.5

Answer:

You can buy 0.5 kilograms of apricots for 240 rubles.
