Leave everything and just check the and gate. It has 3 inputs in the circuit right!
The output of and the gate will be true only if all of its inputs are 1.
Then, check all the 3 inputs to where those were connected.
1st input ----to positive output Q0.
2nd input-----to negative output Q1.
3rd input-------to positive output Q2.
We are taking 2nd input from the bubble i.e., negative that means the original output Q2 shoud be 0 to give 1 after complementing.
This gives the answer 101 5, 5.

No of flip flops are 3 because flip flop is a one-bit storage element. So, the answer is 5 (101).
