If we want to represent 8 base 10 then it will be represented as follows:

A) 7421 code    8(10)= 7+1 = 8            1 0 0 1 -> 7 4 2 1 code    1x7+4x0+2x0+1x1=7+0+0+1=8    8(10)=1001(7421)  B) 5421 code    8(10)= 5+2+1     therefore   5 4 2 1                1 0 1 1   8(10)= 1011(5421)  C) 4221 code    8(10)= 4+2+2    therefore 4 2 2 1              1 1 1 0    8(10)= 1110(4221) 

There you go. If this is helpful then please select this as an answer.
