for selective repeat ARQ ,no of bits =6,

(sequence no.=sender window size+reciever window size

 sequence no.=31+31=62

no. of bits required=$\left \lceil log_2 62 \right \rceil$=6 bits )

for GO BACK N ARQ no. of bits =5 bits

( sequence no.=window size+1

                        =31+1=32

no. of bits required =$\left \lceil log_2 32 \right \rceil$=5 bits

i hope u got your all answers.
