a. For the first 200 units: TK 1.9 per unit
b. For the next 100 units: TK 3.0 per unit
c. Beyond 300 units: TK 5.00 per unit
All users are charged a minimum of TK 200 as a meter charge. If the total amount is more than TK 500,
then an additional surcharge of 15% of total amount is charged. Draw a flowchart to take input as
