Radix = R's compliment = 9

-6 7 0

------------

2 1 8 in (R-1)'s compliment

----------

219 in (R)'s compliment but we can't represent 9 in base 9

So after 218 next number will come 220

So 218 + 1 = 220

220 is the final answer

i done like this 670 is in base 9 ..so converted into base 10 = 549 .

Now 9s complement of 549 = 9^3-549 = 180 in base 10 or 220 in base 9

Now 9s complement of 549 = 9^3-549 = 180 in base 10 or 220 in base 9

Why are you doing like this...

Simply find the R-1 compliment

Then give answer accordingly

Why are you changing base and all its too time taking
