Consider the following ckt. given in figure


The present state Q2,Q1,Q0 of the counter before applying the clock pulse was (101). If the input Clock frequency to the circuit is 100KHz, then the output frequency of the circuit will be ?

My Approach: I have build the table from 101 it goes to 010 and from 010 to 101 again so it acts like mod-2 counter But I don’t understand the part in which we’re applying frequency. Can someone help me to visualize it.
