"Solution needed for a Logic Problem"
|
Would you be able to tell me if you have the solution to this Logic Problem. "Billy is twice as old as Sally was when Billy was as old as Sally is now. And the sum of their ages is 28. How old are they now?" This would really help me Thanks Teresa |

Take Billy's age as B and Sally's age as S. then we have: B+S=28 B=2( S-(B-S) ) By deduction, we have that Billy is older than Sally. |
