Question

На конференции по стандартизации некоторого языка программирования участники обсуждают нововведения. Причём каждая тройка участников обсудила ровно одно нововведение между собой и никакие две тройки, различающиеся по составу хотя бы одним участником, не обсуждали одно и то же нововведение. Известно, что за всю конференцию участники обсудили 1330 нововведений. Сколько человек участвовали в конференции по стандартизации?

Answer 3

Problem Analysis

We are given that at a programming language standardization conference, participants discuss innovations. Each group of three participants discusses exactly one innovation among themselves, and no two groups that differ in composition by at least one participant discuss the same innovation. We are also told that a total of 1330 innovations were discussed at the conference. We need to determine the number of participants at the conference.

Solution

Let's assume that there were n participants at the conference. Since each group of three participants discusses exactly one innovation, the number of groups formed will be n/3.

We are also given that a total of 1330 innovations were discussed at the conference. Therefore, the number of groups formed is equal to the number of innovations discussed:

n/3 = 1330

To find the value of n, we can multiply both sides of the equation by 3:

n = 3 * 1330

Now we can calculate the value of n:

n = 3990

Therefore, there were 3990 participants at the conference on programming language standardization.

Answer

There were 3990 participants at the conference on programming language standardization.
