Mr. Raju took the members of his family for a picnic. His father’s mother and mother’s father including each of their child were in one car. His father’s son and sister’s husband, brother’s wife were in second car. He along with his wife, wife’s sister, wife’s brother and son’s wife with a kid was in the third car. How many members of Mr. Raju’s family were there in the picnic and how many were left behind (assuming all members of the third generation are married and Raju had 2 grandparents in the family)?
