John has 10 members of his family on his father's side.  His mother's side is 30% larger.  How many people are there in total?
His mother's side is 10*.3=<<10*.3=3>>3 people larger than his father's side
So his mother's side has 10+3=<<10+3=13>>13 people
So the total number of people is 13+10=<<13+10=23>>23
