3. An electricity board charges the following rates to domestic users to discourage large
consumption of energy.
• For the first 100 units – 50 P per unit
• Beyond 100 units - 60 P per unit
If the total cost is more than Rs.250.00 then an additional surcharge of 15% is added
on the difference. Define a class Electricity in which the function Bill computes the
cost. Define a derived class More_Electricity and override Bill to add the surcharge.
