In a household five tube lights of $40 \mathrm{W}$ each are used for $5$ hours and an electric press of $500 \mathrm{W}$ for $4$ hours every day. Calculate the total electrical energy consumed by the tube lights and press in a month of $30$ days.
 

Two lamps, one rated $60 \mathrm{W}$ at $220 \mathrm{V}$ and other $40 \mathrm{W}$ at $220 \mathrm{V}$, are connected parallel to the electric supply of $200 \mathrm{V}$. Calculate the current drawn from the electric supply.
