Hawking radiation

[S.Owais ismail]

How can black hole lose mass by radiating virtual particles of mass equal to the particle it sucks into it as emission and addition of particle is balanced how it loses mass then ?

It's Hawking Radiation. And it doesn't radiate anything from within the RH of the BH. Rather it is based on the quantum effect of virtual particles being created just this side of the EH, with one falling in and the other escaping. The escaping particle becomes real and is seen as Hawking Radiation, while the other particle to counter the conservation law subtracts from the overall mass of the BH.

The highlighted RH, should be EH...Event Horizon.
