Can you position all of the 9 different circles in the following 3x3 grid in accordance with the 7 statements bellow (it is possible)?
#1. All of the spotted circles each occupy a corner position.
#2. The plain red circle and the striped red circle are in the same column.
#3. The spotted red circle is one position bellow the striped green circle.
#4. The plain blue circle is one position above the plain red circle.
#5. The spotted blue circle and striped blue circle are in the same column.
#6. The striped blue circle is in the top row.
#7. The plain green circle is somewhere to the right of the plain blue circle in the same row.
Additional comment: all the circles must occupy a position in the grid with no more then one circle in any one position.
Here is the solution (Tongueout)
I hope I didn't make any careless mistake...
Attached is the Excel document with the steps :)
Edit : I forgot to put the meaning...
1st letter :
- S = spotted
- T = striped
- P = plain
2nd letter :
- R = red
- B = blue
- G = green
Well done. Great method too.
