P=VI
= 220*10
= 2200

E=P*T
=2200*5
= 11 KWH

11*30 = 330
330* 2.50= RS.825

Current drawn=10A

Voltage=220V

Time=5hr

Electric energy consumed = VIt = 220×10×5

11000Wh = 11KWh

Energy consumed in one day = 11KWh

Energy consumed consumed in 30 days = 11×30 = 330KWh

Cost of one KWh = Rs 2.50

Cost of 330KWh= 330×2.50 = Rs. 825
