Both resistors in series R = 15+5 = 20.
V = 20.
V = IR.
I = V/R = 20/20.
I = 1 A.
V = 20.
V = IR.
I = V/R = 20/20.
I = 1 A.

At t=0 there is no flow of current through inductor because inductor does not allow sudden change in current. So v=IR, I=20/20=1A.

At t <0, no current will be there in the inductor.
As inductor doesn't allow the sudden change in current, the across it immediately after the switch is closed is zero.
