Answer 1

ANSWER:

Rs. 3,27,600

Explanation:

We have,

1. 480 bulbs of 50W

-->Electricity consumed by bulbs in one hour is 480*50=24000WH=24KWH

2. 250 fans of 100W

-->Electricity consumed by fans in one hour is 250*100=25000WH=25KWH

3. 8 heaters of 2000W

-->Electricity consumed by heaters in one hour is

2000*8=16000WH=16KWH

Electricity consumed by all appliances in an hour is 24+25+16=65KWH

Electricity consumed by all appliances in a day is 65*8=520KWH

Electricity consumed by all appliances in a month is 520*30=15600KWH

Electricity consumed by all appliances in a quarter of year is 15600*3=46800KWH

Here, we got units consumed in quarter of year i.e. 46800KWH

Cost of units consumed is 46800*7=Rs.3,27,600.
