Question

В магазине имеется крупа трёх видов: перловка, рис, овсянка — всего 607 кг, Если бы продали 44 кг перловки, 18 кг риса и 29 кг овсянки, то масса круп всех видов стала бы одинаковой. Сколько килограммов крупы каждого вида имеется в магазине? Ответ: В магазине перловки П кг, риса КГ, Овсянки КГ.​

Answer 1

1)607-44-18-29=516

2)516:3=172

3)172+44=216кг.перловки

4)172+18=190кг.риса

5)172+29=201 кг.овсянки

Answer 2

To solve this problem, we can set up a system of equations based on the given information. Let's denote the amount of pearl barley as P kg, the amount of rice as R kg, and the amount of oatmeal as O kg.

From the problem, we know that the total weight of all three types of cereal is 607 kg:

P + R + O = 607 kg ---(1)

We also know that if 44 kg of pearl barley, 18 kg of rice, and 29 kg of oatmeal were sold, the weight of all three types of cereal would be equal:

(P - 44) + (R - 18) + (O - 29) = (607 - 44 - 18 - 29) kg P + R + O - 44 - 18 - 29 = 516 kg P + R + O = 607 - 44 - 18 - 29 + 516 kg P + R + O = 1032 kg ---(2)

Now we have a system of equations (1) and (2) that we can solve to find the values of P, R, and O.

Subtracting equation (1) from equation (2), we get:

(P + R + O) - (P + R + O) = 1032 - 607 0 = 425

This equation is not possible, which means there is no solution that satisfies the given conditions. Therefore, it is not possible to determine the amount of each type of cereal in the store based on the given information.
