Girls age:
If multiplying their ages yields 36, then their ages must fall into one of the eight categories below:
36 = 2 3 6, and when these ages are added together, we get 11.
36 = 2 2 9, and when these ages are added together, we get 13.
36 = 4 9 1, and when these ages are added together, we get 14.
36 = 4 3 3, and when these ages are added together, we get 10.
36 = 18 2 1, and when these ages are added together, we get 21.
36 = 12 3 1, and when these ages are added together, we get 16.
36 = 6 6 1, and when these ages are added together, we get 13.
36 = 36 1 1, and when these ages are added together, we get 38.
Since 2 + 2 + 9 Equals 13, as does 6 + 6 + 1, we’re left with two options. This is when the seemingly insignificant remark that “the oldest sister is blonde” comes in handy. This phrase denotes the existence of an elder sister who is not a twin. As a result, only the first equation is valid. As a result, the eldest sister is 9 years old, while the younger sisters are both 2.
