Answer :
Answer:
Ivan and Gavin will meet 15th day.
Step-by-step explanation:
Given:
On every 3rd Ivan goes to gym and every 5th day Gavin goes to the gym.
We need to find when Ivan and Gavin will go the gym at the same time.
Here we need to find the Least Common Multiple (LCM) of 3 and 5.
3 = 1 * 3
5 = 1 * 5
LCM of 3 and 5 is 1*3*5 = 15
So, Ivan and Gavin will meet 15th day.
