Lets Use the following notations

B=Football

C=Clock

F=Fan

First equation gives B=6

Second Equations gives C=3

Third Equations Gives F*F-F=6=>F(F-1)=6 => F=3

Last equation, one need to watch it very carefully.

Clock with time 3 = 3. So Clock with time 2 = 2

Similarly Football with 6 black dots = 6. So with 3 black dots=3

Fan with three blades = 3. So with 2 blades = 2.

So the last equation becomes

2*3-2=6-2=4

So the answer is 4.
