Given information: - Sally (a girl) has 3 brothers. - Each brother has 2 sisters.
Since Sally is a girl, and she has 3 brothers, it means that each of her brothers considers her as one of their sisters.
Therefore, if each brother has 2 sisters, and Sally is one of those sisters for each brother, then Sally has 1 other sister besides herself.
So, the number of sisters Sally has is 1.

To solve this problem, we need to find the number of sisters Sally has.
Given information:
Sally has 3 brothers. Each brother has 2 sisters. Since Sally is a girl, she is not counted as a sister to her brothers.
Step 1: Find the total number of sisters for all 3 brothers. Number of sisters for each brother = 2 Total number of sisters for all 3 brothers = 3 × 2 = 6
Step 2: Since Sally is not counted as a sister to her brothers, the number of sisters Sally has is the total number of sisters for all 3 brothers minus Sally herself. Number of sisters Sally has = Total number of sisters for all 3 brothers - 1 Number of sisters Sally has = 6 - 1 = 5
Therefore, Sally has 5 sisters.
