Why I am not studying???

Because :

No Study  =  Fail ....................... ( I )

Study   =  No Fail ............................ ( II )

By Combining ( I ) & ( II ) :

=====>  ( No Study  + Study )  = ( No Fail  +  Fail )

By Taking ( Study ) as a common factor in the left hand side
And Taking ( Fail ) as a common factor in the right hand side

=====> Study ( No + 1)  =  Fail (No + 1 )

By Dividing both sides by ( No + 1)

=====> Study = Fail    

  
SO I ADVISE YOU TO STOP STUDYING
