Explanation

The family has: 1 mother + 1 father + 7 daughters + 1 brother (the same brother for all daughters) = 10 people total. The key insight is that 'each daughter has 1 brother' means there is one male child who is the brother to all 7 sisters.

AI explanation

To answer this question, let's break down the information given:

The Smith family has:

  • Mother
  • Father
  • 7 daughters
  • Each daughter has 1 brother

From this information, we can deduce that there is only 1 brother for all the daughters. Therefore, there is only 1 son in the family.

To calculate the total number of people in the family, we add up the number of family members:

  • Mother: 1
  • Father: 1
  • 7 daughters: 7
  • 1 son: 1

So, the total number of people in the family is 1 + 1 + 7 + 1 = 10.

Therefore, the correct answer is option C) 10.
