Since it is cascaded i guess output q from 1st jk flip-flop drives clock of 2nd flip-flop. So if we assume initially q2q1=00.
Then further count sequence will be 11..10...01...00.
Then further count sequence will be 11..10...01...00.

Since the flip-flop is in toggle state(j=k=1), count starts from 00, 11, 00, 11, 00. So after the fourth pulse the state is 00.

Every O/P repeats after its mod here mod is 4 so after 4 clk pulses the O/P repeats i.e. 00.
