Calculating the Cost of Watermelon

To calculate the cost of the watermelon, we can use the given information about the prices of different combinations of fruits.

Given: - Cost of watermelon, pineapple, and pumpkin = 1390 Rubles - Cost of watermelon, pineapple, and pumpkin = 940 Rubles - Cost of watermelon, pineapple, and pumpkin = 1220 Rubles - Cost of watermelon and pineapple = 700 Rubles

Let's calculate the cost of the watermelon.

Solution:

1. From the given information, we can deduce the following equations: - (Watermelon + Pineapple + Pumpkin) = 1390 Rubles - (Watermelon + Pineapple + Pumpkin) = 940 Rubles - (Watermelon + Pineapple + Pumpkin) = 1220 Rubles - (Watermelon + Pineapple) = 700 Rubles

2. Subtracting the fourth equation from the first equation gives us the cost of the pumpkin: - (Watermelon + Pineapple + Pumpkin) - (Watermelon + Pineapple) = 1390 Rubles - 700 Rubles - Pumpkin = 690 Rubles

3. Now, we can use the cost of the pumpkin to find the cost of the watermelon: - (Watermelon + Pineapple + Pumpkin) - (Pineapple + Pumpkin) = 1390 Rubles - 940 Rubles - Watermelon = 450 Rubles

Answer:

The cost of the watermelon is 450 Rubles.
