Question 871038: The sum of 3 brothers's age is 27.
Two of the brothers are twins.
How old is other one?
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! A + 2B = 27
Since there are two with the same age, A must be an odd number.
Possibilities:
If the twins are 1, then the other is 25
If the twins are 2, then the other is 23
If the twins are 3, then the other is 21
If the twins are 4, then the other is 19
If the twins are 5, then the other is 17
If the twins are 6, then the other is 15
If the twins are 7, then the other is 13
If the twins are 8, then the other is 11
If the twins are 9, then the other is 9 (biologically possible, but unlikely)
If the twins are 10, then the other is 7
If the twins are 11, then the other is 5
If the twins are 12, then the other is 3
If the twins are 13, then the other is 1
.
The answer is that the other is any odd numbers from 1 to 25.
