1. Open the left cabinet above the table + machine on the table, + 3 drawers. Take the 2 small bottles from the two cabinets, 1 blood sample dish from the machine, and 3 items from the 3 drawers.

2. Go all the way to the right side of the room and take the piece of paper stuck between the two black bottles (on same shelf as big green bottle).

3. Use the blood sample dish, and two pieces of the microscope on the microscope.
5. Using what you just found, look at all six slides on the microscope and count the total.
Aska = 1 white dot, 2 black dots, and 2 weird dots = 9 
4. Now look at the paper you got.
Solve the problem. For solving this, just say the white dot is A, black dot is B, and weird dot is C. First dish = 12, so 2A+2B+2C = 12. Divide both sides by 2. A+B+C = 6 Second dish = 14, so 2A+2B+4C = 14. Divide both sides by 2. A+B+2C = 7 Third dish = 10, so A+3B+C=10 Using the first equation, A+B+C=6, you can get C=6AB Put that into the third equation to get A+3B+6AB=10. Then you get 2B+6=10, 2B=4, B=2. Now that you have B, plug in A=6BC (from first dish) and B=2 into the second equation, A+B+2C=7 to get 62C+2+2C=7. Simplify it and you'll get C=1. Plug B=2 and C=1 into A+B+C=6 to get A+2+1=6. Finally you get A=3. A=White dot=3, B=Black dot=2, C=Weird dot=1. 
12. Look at the chart on the wall and match up each blood type to each person and the numbers you found from the microscope.
A = Ruly = 9 B = Miro = 7 AB = Sila = 6 RH O = Uj = 6 O = Max = 5 RH A = Aska = 9 
13. Now go to the keypad and enter the numbers following the clue above the numpad:
RHO, A, B, RHA, O AB 6, 9, 7, 9, 5, 6 Press the door to open it.
