Arun bro After reading all the reviews i find a way to solve the problem of supersu.
(Error message -
If you just upgraded to Android 4.3, you need to manually re-root your device!"
or
There is no SU binary installed, and SuperSU cannot install it. This is problem! If you upgraded to Android 5.0, you will need to manually re-root your device!")
It is very simple, just download a UPDATE-SuperSU-v2.46, restart your phone in recovery mode and install it.

Reboot your phone normally.
Start supersu app or you have to download it from play store free of cost or if you already have that app update it and after that go to settings uncheck Enable Superuser and then again check it.

Now go to root checker app
(if you dont have it, install it from play store)
and grant permission and done.

note : you should paste UPDATE-SuperSU-v2.46 in your sd card
