IN THIS QUESTION WHILE DOING  

ANSWER OF   

see 0570 mean its in octal . 

so 000 101 111 000  

now >>4 means 010 111 

now <<6 means 010 111 000 000 = 2700 

HE TOOK 0570 AND CONVERTED TO BINARY AND THEN GETTING 2700 IN OCTAL BUT WHEN I AM TAKING 570 NOT TAKING MSB 0 THEN ANSWER IS DIFFERENT ..WHY WHAT IS THE REASON IS THE MSB 0 IS NOT FOR SAYING IT IS OCTAL NUMBER OR WE NEED TO CONSIDER IT.?
