The problem about cats seems to be incorrect. So, I want to post the new one which has the right soulution and doesn't need knowing math. This one is like the riddle about a fisherman but easier. I believe you will cope with it. Good Luck!Thanksgiving DinnerSusan has invited her family to Thanksgiving Dinner. As her plates are not the best, Susan wants to buy new plates – one for each person at her Thanksgiving Dinner.There’ll be a grandfather, a grandmother, two fathers, two mothers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, one father-in-law, one mother-in-law and a daughter-in-law.At least how many plates does Susan need to buy?
Hi Tanya,
I think there are seven members in Susan's family.
"a grandfather, a grandmother, two fathers, two mothers, one father-in-law, one mother-in-law and a daughter-in-law" are 4 members: grandfather, grandmother, a wife and a husband.
"four children, three grandchildren, one brother, two sisters, two sons, two daughters" are 3 members: one son and two daughters.

maybe 11
if I have counted correctly, there should be 7 persons.
It's 7 I think.
