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?
Let's think step by step.
23
His mother's side is 10 *.

3 = 3 people larger than his father's side.

So his mother's side has 10 + 3 = 13 people.

So the total number of people is 13 + 10 = 23.

.

So, the answer is 23
