Question

Решите пожалуйста задачу . Туристы израсходовали в походе 230 стаканов крупы . Риса было израсходовано в 2 раза меньше , чем манной крупы , и на 30 стаканов меньше , чем гречневой крупы . Сколько стаканов риса израсходовали туристы ?

Answer 1

Пусть х- стаканы риса
2х- манная крупа
х+30 гречневая крупа
Всего израсходовано 230 стаканов.
--------------------------------------------------
Составим уравнение и решим его.
х+2х+(х+30)=230
4х=230-30
4х=200
х=200/4
х=50
-----------------------------
50-стаканы риса
100-манная крупа
80-гречневая крупа
Ответ:50, 100, 80.
-----
1)(230-30):2=100(ст) манная крупа
2)100:2=50(ст) риса
3)50+30=80(ст) гречневая крупа.

Problem Analysis

To solve this problem, we need to determine the number of cups of rice that the tourists consumed during their trip. We are given the following information: - The tourists consumed 230 cups of groats (manna kasha). - The amount of rice consumed was half the amount of groats consumed. - The amount of rice consumed was 30 cups less than the amount of buckwheat groats consumed.

Let's solve this step by step.

Solution

Let's assume the number of cups of rice consumed is x.

According to the given information: - The amount of rice consumed is half the amount of groats consumed: x = (1/2) * 230. - The amount of rice consumed is 30 cups less than the amount of buckwheat groats consumed: x = (230 - 30).

We can equate these two expressions for x and solve for the value of x.

Calculation

Let's calculate the value of x using the given information.

1. The amount of rice consumed is half the amount of groats consumed: - x = (1/2) * 230 - x = 115

2. The amount of rice consumed is 30 cups less than the amount of buckwheat groats consumed: - x = (230 - 30) - x = 200

By equating the two expressions for x, we find that 115 = 200, which is not possible. Therefore, there seems to be an inconsistency in the given information.

Please double-check the problem statement or provide any additional information if available.
