Question

please answer this question fast by solving it.........​

Answer 1

P=1100W

t=2 hr

P=Energy/time

1100×2=energy

2200w/hr

=2.2kw/h

When use for 30 days = 2.2×30

= 66kw/hr

cost of 1 unit = ₹5

cost of 66unit = 5×66

= ₹330 Ans

Answer 2

Answer:

• Electrical Expenses is Rs. 330.

Given:

1. Power of Electric Iron (P) = 1100 W.
2. Time For it is Consumed Daily (t) = 2 hours.
3. Charge of unit Energy = Rs. 5 per unit

Explanation:

$\rule{300}{1.5}$

As we Know, The Given Power I.e. 1100 W.

Power Consumed in 2 hours.

$\large\bigstar \: {\boxed{\tt E_{(Day)} = P \times t}}$

$\bold{Here}\begin{cases}\tt{E_{(Day)}} \text{ Denotes Electrical Energy Consumed For a hour} \\ \text{P Denotes Power} \\ \text{t Denotes Time taken}\end{cases}$

Now,

$\large{\boxed{\tt E_{(Day)} = P \times t}}$

Substituting,

$\large{\tt \hookrightarrow E_{(Day)} = 1100 \: W \times 2 \: h}$

$\large{\tt \hookrightarrow E_{(Day)} = 1100 \times 2}$

$\large{\tt \hookrightarrow E_{(Day)} = 2200 \: Wh}$

• 1wh = 10⁻³ Kwh.

$\large{\tt \hookrightarrow E_{(Day)} = 2200 \times 10^{-3} \: Kwh}$

$\large{\tt \hookrightarrow E_{(Day)} = 2.200 \; Kwh}$

• 1 unit = 1 Kwh.

Substituting, Gives

$\large\hookrightarrow{\underline{\boxed{\tt E_{(Day)} = 2.200 \: unit}}}$

$\rule{300}{1.5}$

$\rule{300}{1.5}$

Above Electrical Consumption is For an Day.

Let's Find out it For 30 days (April Month)

$\large{\tt \hookrightarrow 1 \: day \xrightarrow{} 2.2 \: unit}$

$\large{\tt \hookrightarrow 30 \: day \xrightarrow{} 30 \times 2.2 \: unit}$

$\large\hookrightarrow{\underline{\underline{\tt 30 \: day \xrightarrow{} 66 \: unit}}}$

Note:-

• April has 30 days in a Month.

$\rule{300}{1.5}$

$\rule{300}{1.5}$

As stated in Question.

1unit = Rs 5.

$\large{\tt \hookrightarrow 1 \: unit \xrightarrow{} Rs \: 5}$

$\large{\tt \hookrightarrow 66 \: unit \xrightarrow{} Rs \: 66 \times 5}$

$\large\hookrightarrow{\underline{\boxed{\red{\tt 66 \: unit \xrightarrow{} Rs \: 330}}}}$

∴ Electrical Expenses For the April Month is Rs. 330.

$\rule{300}{1.5}$
