Answer 2

➤ Given :-

Original price of room cooler :- ₹ 3600

Increase percentage :- 20%

➤ To Find :-

New price of the room cooler

➤ Solution :-

First, we should find the value of the increased percentage in the numerical format by finding 20% of 3600

${\tt \longrightarrow 20 \bf\% \tt \: \: of \: \: 3600}$

${\tt \longrightarrow \dfrac{20}{100} \times 3600}$

${\tt \longrightarrow \dfrac{20}{\cancel{100}} \times \cancel{3600} = \boxed{\tt 20 \times 36}}$

${\tt \longrightarrow \boxed{\tt Rs \: \: 720}}$

Now,

New price :-

${\tt \longrightarrow 3600 + 720}$

${\tt \longrightarrow Rs \: \: 4320}$

$\Huge\therefore$ The new price of the room cooler is ₹ 4320.
