   The given expression
   

   = 999	995	× 999
   	999

   
   

   =		999 +	995		999
   			999

   
   

   = 999 × 999 +	995	× 999
   	999

   
   = (1000 – 1) 999 + 995
   = 999000 – 999 + 995
   = 999000 – 4 = 998996

   Correct Option: B

   The given expression
   

   = 999	995	× 999
   	999
