Annual fixed charges due to maximum demand corresponding to triff(b)=Rs 30000
Annual running cost due to kWh consumed=Rs 199680
Total charges/annum for tariff(b) = Rs 236880
maximum demand corresponding to tariff(a) = 950 kVA
Annual fixed charges=Rs 30400
Annual running charges for kWh consumed = Rs 189696
Total charges/annum for tariff(a) = Rs 220096
