I tried Sonnet also, to no avail:

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.
