One visits every 3rd day
Second visits every 7th day
Now, today they both visits Harry's store.
We need to find the next day when both visit the same day.
We will need to find LCM of 3 & 7, which is 21
So, on 21st day from today they both will visit the store.
Answer D

One distributor visits every 3rd day and other every 7th day
So, they will meet on a day which is a multiple of both 3 and 7 => LCM (3,7) = 21st day
So, Answer will be D
Hope it helps!
