Answer 1

Пусть х это будет 1кг огурцов тогда помидоры будут 2х
купили всего 2кг огурцов и 1 кг помидоров то это 4х
4х - 40%
750-100%
4х=750*40/100
4х=300
х=75

Answer 2

Problem Analysis

To solve this problem, we need to find the price per kilogram of cucumbers given that they are a certain percentage cheaper than tomatoes. We are given that the total cost of 2 kg of cucumbers and 1 kg of tomatoes is 40% of the total amount of money the mother had, which was 750 rubles. We also know that cucumbers are cheaper than tomatoes.

Solution

Let's assume the price per kilogram of tomatoes is x rubles. Since cucumbers are cheaper than tomatoes, the price per kilogram of cucumbers can be expressed as kx, where k is a constant factor representing how much cheaper cucumbers are compared to tomatoes.

We can set up the following equation based on the given information:

2 * (kx) + 1 * x = 0.4 * 750

Simplifying the equation:

2kx + x = 300

Factoring out x:

x(2k + 1) = 300

Solving for x:

x = 300 / (2k + 1)

Therefore, the price per kilogram of cucumbers is 300 / (2k + 1) rubles.

Answer

The price per kilogram of cucumbers is 300 / (2k + 1) rubles, where k represents the constant factor by which cucumbers are cheaper than tomatoes.
