Question 1209045
.
If I give my brother $5$ dollars, then we will have the same amount of money.  If instead he gives me 
$12$ dollars, then I'll have four times as much money as he will have.  How much money does my brother 
currently have (in dollars)?

As worded,  printed,  posted and presented,  this problem is mathematically  FATALLY  DEFECTIVE,

since it has no a precise solution in integer number of cents.


In such problems,  their meaning  ALLWAYS  assumes a precise solution;  approximate solutions 

with non-integer number of cents are not appropriate,  are not accepted and can not be accepted.
