Look at the top left of the screen. There are two numbers in white ink written on a red background. If you combine the colors (red + white) you get “Pink”. And if you divide the number 27 by 9 you get 3. Hence, the windmill on the left is pink in color and ahs 3 blades. Using this logic, you can figure out this puzzle. The numbers on the right are written in blue ink on a red background. So if you combine these colors you get “Purple”. And if you divide 25 by 5 you get 5. So the windmill on this side should have 5 blades and the color should be purple.
So change the white color of the blades in such a way that only 5 blades are in purple with white gaps in between them. Once this is done, a key will be revealed. Use it to unlock the door and escape.
