Answer :

Power in the secondary coil: PS = 60 W
Current through the secondary coil: IS = 0.54 A
Voltage in the primary coil: Line voltage = VP = 220 V
Formula used:
Power is given as
Where V is the voltage and I is the current flowing.

Here, VS is the Voltage in the secondary coil, PS is the power of the secondary coil and IS is the current through the secondary coil

VS = 111.11 V
Since VS < VP, transformer is a step down transformer.
We know that proportions

Hence current through the primary coil is 0.272 A.
