Problem Analysis

To solve this problem, we need to find the price of 1 kilogram of grapes. We are given that the price of grapes is 3 times higher than the price of apples. Additionally, we know that 4.5 kilograms of apples and 2.5 kilograms of grapes were purchased for a total of 336 rubles.

Solution

Let's assume the price of 1 kilogram of apples is x rubles. According to the given information, the price of 1 kilogram of grapes is 3 times higher, so it would be 3x rubles.

We can set up the following equation to represent the total cost of the purchase: 4.5x + 2.5(3x) = 336

Now, let's solve this equation to find the value of x.

Solving the Equation

4.5x + 7.5x = 336 12x = 336 x = 336 / 12 x = 28

Therefore, the price of 1 kilogram of apples is 28 rubles.

Since the price of 1 kilogram of grapes is 3 times higher, the price of 1 kilogram of grapes would be 3 * 28 = 84 rubles.

Answer

The price of 1 kilogram of grapes is 84 rubles.
