sir, the energy released during fission is 200 MeV where as energy released in Fusion is 23.5 MeV then why we say that there is more energy release in fusion

You have to look at energy released per unit mass of reactant.

The values mentioned are enrgy released per fission/fusion.
In case of fission it is U-235. SO energy released per unit mass will be 200/235 while in case of fusion it will be 23.5/2(deuterium) or 3 (for tritium)

So energy relased per unit mass is more in fusion.
