Answer 2

Solving the Problem of Vitia and Kostia

To solve the problem of how many tasks Vitia and Kostia solved, we can use the information provided in the question and apply basic algebraic reasoning.

Let's denote: - The number of tasks Vitia solved as V - The number of tasks Kostia solved as K

We are given the following information: 1. Kostia solved 3 times more tasks than Vitia: K = 3V. 2. Vitia solved 18 tasks less than Kostia: V = K - 18.

We can use these two equations to solve for the number of tasks each of the boys solved.

First, we can substitute the value of K from the first equation into the second equation: V = 3V - 18.

Solving for V: V = 18.

Then, we can use the value of V to find K: K = 3 * 18 = 54.

So, Vitia solved 18 tasks and Kostia solved 54 tasks.

Therefore, Vitia solved 18 tasks and Kostia solved 54 tasks.
