Question

An electrical appliance of power 1.5 kW is used for 4 hour each day. the cost of electrical energy consumed in 60 days at the rate of ₹ 6.25 per kWh is​

Answer 1

Answer :

• The cost of electrical energy at the rate of ₹ 6.25 is ₹ 2250.

Explanation ::

To Find :-

• The cost of electrical energy consumed in 60 days

Solution :-

Given that,

• Power of an electrical appliance is 1.5 kW for 4 hours each day.
• Given rate = ₹6.25

Firstly, converting 1.5kW to W,

➠ 1.5 kW = 1500 W

Now, energy consumed in one day is,

➠ 1500 W × 4 hours

➠ 6000 Wh

Therefore, energy consumed in 60 days is,

➠ 6000 Wh × 60

➠ 360000 Wh

Converting 360000 Wh to W,

➠ 360000 ÷ 1000

➠ 360 kWh

According the question,

The cost of the electrical energy at the rate of ₹ 6.25,

➠ ₹ 360 × 6.25

➠ ₹ 2250

The cost of electrical energy at the rate of ₹ 6.25 is ₹ 2250.
