Question

10 electric lamps of 40 W, a TV of 80 W runs 6 hours per day in a house. Find the energy consumed in BOT unit monthly.​

Answer 1

Answer:

79.2 units

Explanation:

Given :

• 10 electric lamps of 40 watts runs 6 hours

• A TV of 80 watts runs 6 hours

To find :

• Energy consumed in units monthly

Per day :

Lamp: 40×6×10 = 2400 watts = 2.4 units

TV : 80×6 = 240 watts = 0.240 units

Daily usage = 2.4+0.24

Daily usage = 2.64

Monthly usage = 2.64 units×30

Monthly usage = 79.2 units

The monthly consumption is 79.2 units

Answer 2

Answer:

Given:

• 10 electric lamps of 40 W, a TV of 80 W runs 6 hours per day in a house.

Find:

• Find the energy consumed in unit monthly.

Calculations:

• Firstly, let's find what's the energy consumed per day.

Daily energy consumption of Lamp:

⇒ $\bold{40 \times 6 \times 10 = (2400 \: W) }$

⇒ ${\sf{\underline{\boxed{\red{\sf{2.4 \: units}}}}}}$

Daily energy consumption of TV:

⇒ $\bold{80 \times 6 = (240 \: W)}$

⇒ ${\sf{\underline{\boxed{\red{\sf{0.240 \: units }}}}}}$

⇒ $\bold{Daily = 2.4 + 0.24}$

⇒ ${\sf{\underline{\boxed{\red{\sf{ Daily = 2.64}}}}}}$

⇒ $\bold{Monthly = 2.64 \times 30}$

⇒ ${\sf{\underline{\boxed{\red{\sf{Monthly = 79.2 \: units}}}}}}$
