Question

В на­ча­ле года число або­нен­тов те­ле­фон­ной ком­па­нии «Север» со­став­ля­ло 200 тыс. чел., а в конце года их стало 210 тыс. чел. На сколь­ко про­цен­тов уве­ли­чи­лось за год число або­нен­тов этой ком­па­нии?

Answer 1

Решение:
Обозначим за 100% число абонентов в 200 тыс.чел
а за х -210 тыс чел абонентов
Составим пропорцию:
200  -  100
210    -  х
х=210*100/200=105 (%)
105%-100%=5% ( на столько процентов увеличилось количество абонентов)

Ответ: 5%

Answer 2

Calculation of Percentage Increase in Subscribers for "Sever" Telephone Company

To calculate the percentage increase in the number of subscribers for the "Sever" telephone company, we need to find the difference between the number of subscribers at the end of the year and the number of subscribers at the beginning of the year, and then divide that difference by the number of subscribers at the beginning of the year. Finally, we multiply the result by 100 to get the percentage increase.

Given information: - Number of subscribers at the beginning of the year: 200,000 - Number of subscribers at the end of the year: 210,000

Step 1: Find the difference in the number of subscribers: 210,000 - 200,000 = 10,000

Step 2: Divide the difference by the number of subscribers at the beginning of the year: 10,000 / 200,000 = 0.05

Step 3: Multiply the result by 100 to get the percentage increase: 0.05 * 100 = 5%

Therefore, the number of subscribers for the "Sever" telephone company increased by 5% during the year.
