Calculation of the Cost of Apricots per Kilogram

To calculate the cost of apricots per kilogram, we need to use the information provided.

According to the given information: - 4 kilograms of apples were purchased for 36 rubles. - 5 kilograms of apricots were purchased.

The total cost of the purchase was 639 rubles.

To find the cost of 1 kilogram of apricots, we can set up a proportion:

Cost of apples / Weight of apples = Cost of apricots / Weight of apricots

Using the given information, we have: - Cost of apples = 36 rubles - Weight of apples = 4 kilograms - Cost of apricots = unknown - Weight of apricots = 5 kilograms

Plugging in the values, we get:

36 rubles / 4 kilograms = Cost of apricots / 5 kilograms

To find the cost of apricots per kilogram, we can cross-multiply and solve for the unknown:

36 rubles * 5 kilograms = Cost of apricots * 4 kilograms

Simplifying the equation:

180 rubles = Cost of apricots * 4 kilograms

Dividing both sides of the equation by 4 kilograms:

Cost of apricots = 180 rubles / 4 kilograms

Calculating the result:

Cost of apricots = 45 rubles per kilogram

Therefore, the cost of 1 kilogram of apricots is 45 rubles.
