Hello guys, I would like to know how this state table is converted to the circuit below.Note there is no other logic gates used (Only 3 flip flops).I can design a MOD-6 circuit using the clear pins of the flip flops but this circuit does not use any clear but it works , I've implemented it.

Look at 7492, does not use clear or additional gates, just 3 J-K FFs for /6
Thanks for the reply mate , but I would like to know how to convert the table into the circuit - suppose in an exam we are asked to implement the circuit in most hardware efficient way, how would I able to come to the circuit above using the table?

Something is screwed up, looks like C is low order, A is high. From Signetics functional drawing of TTL 7492 , matches your truth table. but I couldn't prove it.Divide by 6 00000.jpg
