Answer 1

540000 = 9/10

1) 540000 : 9 * 10 = 600000 (жит) - голубой страны
2) 540000 + 600000 = 1140000 (жит) - розовой и голубой страны
3) 1140000 : 100 * 40 = 456000 (жит) - желтой страны
4) 456000 + 78000 = 534000 (жит) - фиолетовой страны
5) 3000000 - (1140000 + 456000 + 534000) = 870000 (жит) - изумрудного города

Problem Analysis

To solve this problem, we need to find the number of inhabitants in the Emerald City. We are given the following information: - The Pink Country has 540,000 inhabitants, which is 9/10 of the inhabitants of the Blue Country. - The Yellow Country has 40% of the total population of the Pink and Blue Countries. - The Violet Country has 78,000 more inhabitants than the Yellow Country. - The Magic Country has a total population of 3,000,000.

Let's break down the problem step by step and find the number of inhabitants in the Emerald City.

Step 1: Find the number of inhabitants in the Blue Country

The Pink Country has 540,000 inhabitants, which is 9/10 of the inhabitants of the Blue Country. To find the number of inhabitants in the Blue Country, we can set up the following equation:

(9/10)x = 540,000

Solving this equation will give us the number of inhabitants in the Blue Country.

Step 2: Find the number of inhabitants in the Yellow Country

The Yellow Country has 40% of the total population of the Pink and Blue Countries. To find the number of inhabitants in the Yellow Country, we can calculate 40% of the total population of the Pink and Blue Countries.

Step 3: Find the number of inhabitants in the Violet Country

The Violet Country has 78,000 more inhabitants than the Yellow Country. To find the number of inhabitants in the Violet Country, we can add 78,000 to the number of inhabitants in the Yellow Country.

Step 4: Find the number of inhabitants in the Emerald City

The number of inhabitants in the Emerald City is not directly given in the problem. However, we know that the Magic Country has a total population of 3,000,000. The Magic Country includes the Pink, Blue, Yellow, Violet, and Emerald City. To find the number of inhabitants in the Emerald City, we can subtract the populations of the Pink, Blue, Yellow, and Violet Countries from the total population of the Magic Country.

Let's calculate the number of inhabitants in each step using the given information.

Step 1: Find the number of inhabitants in the Blue Country

To find the number of inhabitants in the Blue Country, we can solve the equation:

(9/10)x = 540,000

Simplifying the equation, we have:

9x = 540,0000

Dividing both sides by 9, we get:

x = 540,0000 / 9

Calculating this, we find that the number of inhabitants in the Blue Country is 600,000.

Step 2: Find the number of inhabitants in the Yellow Country

The Yellow Country has 40% of the total population of the Pink and Blue Countries. To find the number of inhabitants in the Yellow Country, we can calculate 40% of the total population of the Pink and Blue Countries.

The total population of the Pink and Blue Countries is:

540,000 + 600,000 = 1,140,000

40% of 1,140,000 is:

0.4 * 1,140,000 = 456,000

Therefore, the number of inhabitants in the Yellow Country is 456,000.

Step 3: Find the number of inhabitants in the Violet Country

The Violet Country has 78,000 more inhabitants than the Yellow Country. To find the number of inhabitants in the Violet Country, we can add 78,000 to the number of inhabitants in the Yellow Country.

The number of inhabitants in the Violet Country is:

456,000 + 78,000 = 534,000

Therefore, the number of inhabitants in the Violet Country is 534,000.

Step 4: Find the number of inhabitants in the Emerald City

To find the number of inhabitants in the Emerald City, we subtract the populations of the Pink, Blue, Yellow, and Violet Countries from the total population of the Magic Country.

The number of inhabitants in the Emerald City is:

3,000,000 - (540,000 + 600,000 + 456,000 + 534,000) = 870,000

Therefore, the number of inhabitants in the Emerald City is 870,000.

Answer

The number of inhabitants in the Emerald City is 870,000.
