➬ Domestic bridges use around 2 kilowatt hours of energy in a day.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline{☢{\red{\pmb{\sf{\: To \: Find :-}}}}}}$

➬ What is the monthly consumption .

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline{☢{\red{\pmb{\sf{\:Solution :-}}}}}}$

${\large\color{pink}{\underline{\sf{Note :}}}}$

➢ A month can have 28 , 30 or 31 days.

So, we will check all the 3 .

━━━━━━━━━━━━━━━━━━━━━━━━━━

❒ Let's Start :

✏ In 28 days :

$\twoheadrightarrow\sf{Consumption \: in \: 1 \: day = 2 \: kwh}$

${\twoheadrightarrow\sf{Consumption \: in \: 28 \: day = 2 \times 28}}$

$\large\red{:{\longmapsto\color{cyan}{\underline{\overline{\sf{ 56 \: kwh}}}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━

✏ In 30 days :

$\twoheadrightarrow\sf{Consumption \: in \: 1 \: day = 2 \: kwh}$

${\twoheadrightarrow\sf{Consumption \: in \: 30\: day = 2 \times 30}}$

$\large\red{:{\longmapsto\color{cyan}{\underline{\overline{\sf{ 60 \: kwh}}}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━

✏ In 31 days :

$\twoheadrightarrow\sf{Consumption \: in \: 1 \: day = 2 \: kwh}$

${\twoheadrightarrow\sf{Consumption \: in \: 31 \: day = 2 \times 31}}$

$\large\red{:{\longmapsto\color{cyan}{\underline{\overline{\sf{ 62 \: kwh}}}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━

❒ Hence :

➢ Consumption in 1 month could be :

${\pink{➳}}{\orange{\text{ 28 days = 56 kwh}}}$

${\pink{➳ }}{\orange{\text{30 days = 60 kwh}}}$

${\pink{➳}} {\orange{\text{31 days = 62 kwh}}}$
