Detailed Solution

A geyser of

2.5 kW

is used

6 h

daily. The electricity rate is

₹ 4

then the cost of electricity consumed in

10

days is

₹ 60

.
The energy consumed by the geyser

E = P \times t

, where

P

is power and

t

is the time.

\Rightarrow E = 2.5 kW \times 6 h

\Rightarrow E = 15 kWh = 15 units

The electricity rate is

₹ 4

per unit, therefore,

Cost of electricity = ₹ 4 \times 15

= ₹ 60

The cost of electricity is equal to

₹ 60
