Richie the Racoon and his family are all going to a family reunion! At the reunion there is a grandmother, a grandfather, two mothers, two fathers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, a mother-in-law, a father-in-law and a daughter-in-law. How many people came to Richie's family reunion?

Answer 1

Seven

Explanation:

We have the following list of people coming to the reunion,

A grandmother = 1

A grandfather = 2

Two mothers = 1 and 3

Two fathers = 2 and 4

i.e. Up until here there are total 4 people - Grandmother, Grandfather, Mother, Father ( 1, 2, 3, 4)

Four children = 4, 6, 7, 8

Three grandchildren = 6, 7, 8

One brother = 6

Two sisters = 7, 8

Two sons = 4, 6

Two daughters = 7, 8

Therefore, in addition to the four people above, one of the child will be the father and so there are 3 grandchildren.

So, number of people added in this step is 3 and total number of people up until here becomes 7.

A mother-in-law = 1

A father-in-law = 2

A daughter-in-law = 3

So, no new family member is added in this step.

Hence, total number of family members coming to reunion are 7 namely Grandmother, Grandfather, Mother, Father, Three children.
