Problem Analysis

We are given that Petya goes to the pool every 3 days, Vasya goes every 4 days, and Kolya goes every 5 days. They all met at the pool on Monday. We need to determine how many days it will take for them to meet again and what day of the week it will be.

Solution

To find the number of days it will take for them to meet again, we need to find the least common multiple (LCM) of 3, 4, and 5. The LCM is the smallest number that is divisible by all three numbers.

The LCM of 3, 4, and 5 is 60.

To find the day of the week they will meet again, we need to count the number of days from Monday. Since Monday is the first day, we count 1, 2, 3, and so on until we reach a multiple of 7. The remainder will give us the day of the week.

Since 60 divided by 7 gives a remainder of 4, they will meet again on the fourth day of the week after Monday, which is Friday.

Therefore, they will meet again in 60 days on a Friday.
