Each tick of the clock generates one sequence number in 0.1 sec
we have 15 bit clock
so, no. of sequences generated by clock = 2^15 =32768 sequence numbers
which will take 0.1 * 32768 =3276.8 sec by clock
now Lifetimeof the packet is 60 sec and in 60 sec it can eat 300seq numbers so it eats one seq no. in (60/300) =0.2 sec
now to finish 32768 seq no. it will take
0.2*32768
=6553.6 sec . but answer is not matching:(
approx. it is close to option (4)
can u plz tell the answer...
