on taking any 3 digit no. for eg- 100, and after doing all the steps the answer would be 100100
on taking another eg -124 the answer would be 124124
similarly on multiplying 550 the answer would be 550550
hence we can say that if we multiply any 3 digit no.(say 300) with 11 and then the product by 91 then the answer will always be a six digit no. consisting of the 3 digit no. ( 2 times) that we thought (300300)
