Questions:

ReplyDeletewhat do you mean by family? I am adopted and I consider my friends as an important part of my family.

Assuming the following:

Grandfather + Mother + elder brother + myself + my cat = 40 x 5 = 200

Grandmother = 80

Mother = 50

Me = 12

Brother = 28

Cat = x based on cat yrs

1 pair of twin daughters 15 years old = 30 years

ReplyDelete1 grandparent = 85 years

father = 45 years

mother =40 years

I'm mathematically challenged
