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. |
