Calculation of the Cost of Different Quantities of Biscuits

To calculate the cost of different quantities of biscuits, we need to know the price per kilogram. According to the information provided, 1 kilogram of biscuits costs 25 1/5 hryvnias.

Let's calculate the cost of different quantities of biscuits:

1. 1/4 kg of biscuits: To calculate the cost of 1/4 kg of biscuits, we need to find 1/4 of the price of 1 kg of biscuits. The cost of 1/4 kg of biscuits is (1/4) * (25 1/5) hryvnias.

2. 1/2 kg of biscuits: To calculate the cost of 1/2 kg of biscuits, we need to find 1/2 of the price of 1 kg of biscuits. The cost of 1/2 kg of biscuits is (1/2) * (25 1/5) hryvnias.

3. 3/4 kg of biscuits: To calculate the cost of 3/4 kg of biscuits, we need to find 3/4 of the price of 1 kg of biscuits. The cost of 3/4 kg of biscuits is (3/4) * (25 1/5) hryvnias.

4. 7/10 kg of biscuits: To calculate the cost of 7/10 kg of biscuits, we need to find 7/10 of the price of 1 kg of biscuits. The cost of 7/10 kg of biscuits is (7/10) * (25 1/5) hryvnias.

Now let's calculate the costs using the given price of 25 1/5 hryvnias per 1 kg of biscuits.

1. 1/4 kg of biscuits: The cost of 1/4 kg of biscuits is (1/4) * (25 1/5) hryvnias. Calculating this, we get: (1/4) * (25 1/5) = 25 1/20 hryvnias.

2. 1/2 kg of biscuits: The cost of 1/2 kg of biscuits is (1/2) * (25 1/5) hryvnias. Calculating this, we get: (1/2) * (25 1/5) = 12 3/10 hryvnias.

3. 3/4 kg of biscuits: The cost of 3/4 kg of biscuits is (3/4) * (25 1/5) hryvnias. Calculating this, we get: (3/4) * (25 1/5) = 18 3/20 hryvnias.

4. 7/10 kg of biscuits: The cost of 7/10 kg of biscuits is (7/10) * (25 1/5) hryvnias. Calculating this, we get: (7/10) * (25 1/5) = 17 1/10 hryvnias.

Therefore, the cost of 1/4 kg of biscuits is 25 1/20 hryvnias, the cost of 1/2 kg of biscuits is 12 3/10 hryvnias, the cost of 3/4 kg of biscuits is 18 3/20 hryvnias, and the cost of 7/10 kg of biscuits is 17 1/10 hryvnias.

Please note that the provided information did not include the exact price per kilogram of biscuits. The calculations are based on the assumption that the price per kilogram is 25 1/5 hryvnias, as mentioned in the question.
