Let
• S = number of sisters in the family (girls)
• B = number of brothers in the family (boys)

Given

  1. Sally has 3 brothers ⇒ B = 3.
  2. Each brother has 2 sisters ⇒ every boy sees exactly 2 girls in the sibling group.
    Therefore S = 2.

Since Sally herself is one of those 2 sisters, the number of sisters Sally has (other than herself) is

2 – 1 = 1.

Sally has 1 sister.
