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 on which day of the week.

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. This means that they will meet again after 60 days.

To determine which day of the week they will meet again, we need to count the number of days from Monday. Since 60 is divisible by 7 (the number of days in a week), the remainder will be 0. This means that they will meet again on the same day of the week, which is Monday.

Therefore, they will meet again in 60 days, and it will be on a Monday.

Answer

They will meet again in 60 days, and it will be on a Monday.
