0 How SDB Infrastructure Pvt. Ltd. calculated power backup bill in Somdatt Landmark Sector-116

The bill calculated by the company -- as

Description	Total No. Unit Consumed	Initial Reading	Current Reading	Rate (Per Unit(Rs.)	Amount(Rs.)
Power Back Up Charges (Flat No- 403 Ruby Tower No-06)	68	4	64	12.6	806
Add: Service Tax @10%					81
Add: Cess 2%					2
Add: Sec. Cess 1%					1
Total					890

The bill should be instead of this:

 Unit consumed = current reading - initial reading

                          = 64 - 4

                       = 60   instead of 68 they written

Total bill                      = 60*12.60

                                 =  Rs. 756/-  instead of Rs. 806/- and NO tax applicable on it.
