Question

На Укр:Богдан купив пенал за 85 грн., що склало 40%, які у нього було. Скільки грошей було у Богдана? На Русс: Богдан купил пенал за 85 рублей., это сложило 40%, каких у него было. Сколько денег было у Богдана?(я плохо знаю Русс)

Answer 1

Просто составляешь пропорцию. Допустим у Богдана изначально было Хгрн, тогда:

Хгрн — 100%
85грн — 40%

Х = (85*100)/40 = 212,5

Answer 2

Problem Analysis

We have two scenarios: one in Ukrainian and one in Russian. In both scenarios, Bogdan bought a pencil for 85 currency units, which represents 40% of his total money. We need to find out how much money Bogdan had before buying the pencil in each scenario.

Ukrainian Scenario

Bogdan bought a pencil for 85 hryvnias, which represents 40% of his total money. We need to calculate how much money Bogdan had before buying the pencil.

Let's assume Bogdan's total money before buying the pencil is represented by the variable "x" in hryvnias.

According to the given information, the price of the pencil (85 hryvnias) is 40% of Bogdan's total money. We can set up the following equation:

85 = 0.4 * x

To find the value of "x," we can divide both sides of the equation by 0.4:

x = 85 / 0.4

Now we can calculate the value of "x" to find out how much money Bogdan had before buying the pencil.

Russian Scenario

Bogdan bought a pencil for 85 rubles, which represents 40% of his total money. We need to calculate how much money Bogdan had before buying the pencil.

Let's assume Bogdan's total money before buying the pencil is represented by the variable "y" in rubles.

According to the given information, the price of the pencil (85 rubles) is 40% of Bogdan's total money. We can set up the following equation:

85 = 0.4 * y

To find the value of "y," we can divide both sides of the equation by 0.4:

y = 85 / 0.4

Now we can calculate the value of "y" to find out how much money Bogdan had before buying the pencil.

Calculation

Let's calculate the values of "x" and "y" to find out how much money Bogdan had before buying the pencil in each scenario.

For the Ukrainian scenario: x = 85 / 0.4

For the Russian scenario: y = 85 / 0.4

Now we can calculate the values of "x" and "y" using a calculator or by performing the division manually.

Answer

Based on the calculations, we can determine how much money Bogdan had before buying the pencil in each scenario.

In the Ukrainian scenario, Bogdan had 212.5 hryvnias before buying the pencil.

In the Russian scenario, Bogdan had 212.5 rubles before buying the pencil.

Please note that the calculations are based on the given information and the assumption that the price of the pencil represents 40% of Bogdan's total money.
