  • Question
  • In a family, each daughter has the same number of brothers as she has sisters and each son has twice as many sisters as he has brothers. How many sons are there in the family?


  • Options
  • A. 2
  • B. 3
  • C. 4
  • D. 5

  • Correct Answer


  • Explanation
    Let d and s represent the number of daughters and sons respectively.

    Then, we have :

    d - 1 = s and 2 (s - 1) = d.

    Solving these two equations, we get: d = 4, s = 3.
