Answer 2

To find the average cost per kilogram of fruits, we need to calculate the total cost of all the fruits and then divide it by the total weight of the fruits.

Let's calculate the total cost of the fruits first:

- Mama bought 2.5 kg of apples for 130 rubles. - Mama bought 3.2 kg of pears for 153.6 rubles. - Mama bought 1.2 kg of grapes for 135.6 rubles.

To find the average cost per kilogram, we need to add up the total cost of all the fruits and divide it by the total weight of the fruits.

Total cost of apples = 130 rubles Total cost of pears = 153.6 rubles Total cost of grapes = 135.6 rubles

Total cost of all fruits = 130 + 153.6 + 135.6 = 419.2 rubles

Total weight of all fruits = 2.5 + 3.2 + 1.2 = 6.9 kg

Now, let's calculate the average cost per kilogram of fruits:

Average cost per kilogram = Total cost of all fruits / Total weight of all fruits

Average cost per kilogram = 419.2 rubles / 6.9 kg

The average cost per kilogram of fruits is approximately 60.75 rubles.

Please note that the calculations are based on the given information and may vary depending on the actual prices of the fruits.
