Calculation of the Price of Oranges

To calculate the price of 1 kg of oranges, which is 20% more expensive than 1 kg of bananas priced at 70 rubles, we can use proportions.

Let's assume the price of 1 kg of oranges is x rubles.

According to the given information, the price of 1 kg of bananas is 70 rubles.

We can set up the following proportion:

1 kg of bananas / 1 kg of oranges = 70 rubles / x rubles

To solve for x, we can cross-multiply and solve for x:

1 kg of bananas * x rubles = 1 kg of oranges * 70 rubles

x = (1 kg of oranges * 70 rubles) / 1 kg of bananas

Now, let's calculate the price of 1 kg of oranges using the given information:

x = (1 kg of oranges * 70 rubles) / 1 kg of bananas

x = (70 rubles) / 1

x = 70 rubles

Therefore, 1 kg of oranges costs 70 rubles.

Please note that the calculation assumes a linear relationship between the prices of bananas and oranges and does not take into account other factors that may affect the pricing.
