ELECTRICTY BILL

CALCULATE The Electricity Power Consumption Rate you your personal electricity board, from the number of units consumed this month.

Charges are as follows:

Units of Consumption	Charges / UNIT
1-100	Rs 0.20 / unit in this slot
101-200	Rs. 0.35 / unit in this slot
201-350	Rs 0.50 / unit in this slot
351-400	Rs 0.75 / unit in this slot
401-500	Rs 1.0 /unit in this slot
501 AND ABOVE	Rs 1.25 /unit in this slot

Additionally, you have to calculate Rs. 100 as meter charge and
an 18% GST on total amount.

Input	Output	calculation
50 units	Rs. 10.0	(50 * 0.20)
120 units	Rs. 27.0	(100 * 0.20) + (20 * 0.35)
480 units	Rs. 247.50	(100 * 0.20) + (100 * 0.35) + (150 * 0.50) + (50 * 0.75) + (80 * 1.0)
