Question

В магазине было 320 кг. яблок и винограда. Когда продали 115 кг яблок и 97 кг винограда, то яблок и винограда осталось поровну. Сколько яблок было в магазине первоначально?

Answer 1

х кг - было яблок

у кг - было винограда

х+у = 320, откуда х=320 - у

х-115=у-97, подставим значение х, получим

320-у-115=у-97

320-115+97=2у

2у=302

у=151 кг винограда было

320-151 = 169 кг яблок было

Проверка

169-115=151-97

54=54

Answer 2

Якщо (X+115) - кг Яблок   (X+97) - кг Виноград

Тоді   

(X+115)+(X+97)=320

2X+212=320

2X=320-212

2X=108

X=54

 

54+115=169 кг Яблок

Answer 3

Calculating the Initial Quantity of Apples in the Store

To calculate the initial quantity of apples in the store, we can use the information provided in the question and apply some basic math.

Let's denote: - A as the initial quantity of apples in kilograms - V as the initial quantity of grapes in kilograms

We are given the following information: 1. The total initial quantity of apples and grapes was 320 kg. 2. After selling 115 kg of apples and 97 kg of grapes, the remaining quantities of apples and grapes were equal.

We can set up the following equations based on the given information: - A + V = 320 (equation 1, representing the total initial quantity) - A - 115 = V - 97 (equation 2, representing the remaining quantities being equal)

Solving the Equations

We can solve the system of equations to find the initial quantity of apples (A).

From equation 1: A = 320 - V

Substitute the value of A in equation 2: 320 - V - 115 = V - 97 205 - V = V - 97 205 + 97 = V + V 302 = 2V V = 302 / 2 V = 151

Now that we have the initial quantity of grapes (V), we can find the initial quantity of apples (A): A = 320 - V A = 320 - 151 A = 169

Answer

The initial quantity of apples in the store was 169 kilograms. This calculation is based on the given information and the solution of the system of equations.
