My widowed granny has 3 kids. They are all married with at least 1 kid. my aunt has 3 nephews. What is the minimum number of chairs needed for the dinner

The minimum number of chairs needed for the dinner is 11 chairs

Solution:

Given that,

My widowed granny has 3 kids

Therefore, there is granny and her 3 kids which becomes 4

They are all married with at least 1 kid

The 3 kids are married. Therefore, 3 kids and their partner makes a total of 6 (which means 3 couples)

They are all married with at least 1 kid. My aunt has 3 nephews

So, there are 4 children in total

The minimum number of chairs needed for the dinner is:

granny + three couples + 4 children = 1 + 6 + 4 = 11

Thus 11 chairs are needed for dinner
