Question

Find the cost of using 5KW Air condition unit for 7hrs daily in a month?​

Answer 1

Given:

A 5KW Air condition unit is used for 7hrs daily in a month.

To find:

Total cost?

Calculation:

First , let's calculate the total units of electricity used to operate Air Conditioner for 1 day :

$\rm \: units = power (in \:kW) \times time(in \: hr)$

$\rm \implies\: units = 5\times7$

$\rm \implies\: units = 35 \: kW \: hr$

Now, total units in 1 month :

$\rm \implies\: total \: units = 35 \times 30$

$\rm \implies\: total \: units = 1050 \: units$

Now, let cost be Rs x per unit , so total cost :

$\rm \: total \: cost = 1050 \times x$

$\rm \implies total \: cost =Rs \: 1050 x$

So, net cost is Rs 1050x.

Answer 2

Given:-

A 5KW Air condition unit is used for 7hrs daily in a month.

To Find:-

Total cost?

Calculation:-

First , let's calculate the total units of electricity used to operate Air Conditioner for 1 day :

units=power (in kW)×time(in hr)

units=5×7

units=35 kW hr

Now, total units in 1 month :

total units=35×30

total units=1050 units

Now, let cost be Rs x per unit , so total cost :

total cost=1050×X

total cost=1050x

So, net cost is Rs 1050x.
