One group has 5 people and each person has 1 granola bar another group has 5 people and each person has 0 granola bars which group has more granola bars explain

We can sort this out in 2 groups. Group 1 has 5 people and each person has 1 granola bar. Group 2 has 5 people and each person has 0 granola bars. Alright , so  group 1 has 5 members and each has 5 granola bars, therefore group 1 has altogether 5 granola bars. On the other hand Group 2 has 5 members but with 0 granola bars each. So in result , Group 1 has more granola bars, having 5 and group 2 having 0. Hope this helped!
