Question

If 1unit=rs5 for 30 days, then find out the bill of:

Fridge-5 kw-20 hrs
&
AC-1.5 kw-10 hrs

Answer 1

Hey there! ☺☻☺

Given,
1 unit = Rs. 5 for 30 days

Now,
Energy consumed by fridge in one day = 5*20 = 100 kWh
Energy consumed by AC in  one day = 1.5*10 = 15 kWh
Total Energy consumed in one day = 100 + 15 = 115 kWh

Energy consumed in 30 days = 115*30 = 3450 kWh

Now,
Cost of 1 unit = Rs. 5
Cost of 3450 unit = 3450 * 5
                             =  Rs. 17250
Hope It Helps You! ☺☻☺

****************************

Energy consumed by fridge in one day = 5*20 = 100 kWh

Energy consumed by AC in  one day = 1.5*10 = 15 kWh

Total Energy consumed in one day = 100 + 15 = 115 kWh 

Energy consumed in 30 days = 115*30 = 3450 kWh

                                          Cost of 1 unit = Rs. 5


there are 3450 unit 
therefore, 


                        Cost of 3450 unit = 3450 * 5                     

        =  Rs. 17250
