Enter the previous and current meter readings (Rp, Rc) 2. Calculate total consumption C=RcRp 3. Calculate the consumption charge according to the above table 4. Calculate the total bill value by adding 15% tax into the consumption charge 5. Print the total bill amount Examples: - Rp=2000,Rc=3500,C=1500KWh Charge of 1500KWh=10000.18=180SR Total bill value =1801.15=207SR - Rp=2000,Rc=8500,C=6500KWh Charge of 6500KWh=60000.18+5000.3=1080+150=1230SR
