Answer:Mark Is 9 years old; Christine is 5 years old 
Step-by-step explanation:
 Present age 
 LET  mark age be x
 Christine be x-4 yrs
In 3 yrs Time 
Mark will be x+3 yrs old
Christine  will be  (x -4 +3) = x-1 years old 
Also, In 3 years time 
Christine  = 2/3 Mark
such that 
   x-1 = 2/3(x+3)
   x -1= 2x+6 / 3
     3x  -3= 2x+6
       3X--2X = 6+3
          =X=9
Mark Is 9 years old 
Christine is   x -4 = 9-4=5 years old
