Consider the following scenario An electricity board charges the following rates for the use of electricity:

For the first $200$ units, $80$ Paisa per unit

For the next $100$ units, $90$ Paisa per unit

Beyond $300$ units; $1$ rupee per unit

All users are charged a minimum of Rs$.100$ as meter charge. If the total amount is more than Rs$.400,$ then an additional surcharge of $15\%$ of total amount is charged.

Draw the flow chart and also write a program to read number of units consumed and print the charges based on the above scenario.
