​

Answer 1

➤ Given :-

Cost price :- ₹ 50

Selling price :- ₹ 30

➤ To Find :-

Gain or loss percentage of the given sum.........

➤ Formula required :-

$\large \dashrightarrow \boxed{ \gray{ \mathfrak{ \frac{Loss}{Cost \: price} \times 100 }}}$

➤ Solution :-

Here,

Cost price is greater than selling price......

So,

Loss :-

$\tt \longrightarrow50 - 30$

$\tt \longrightarrow₹20$

Now,

Loss percentage :-

$\tt \longrightarrow \dfrac{20}{50} \times 100$

$\tt \longrightarrow \dfrac{20}{ \cancel{50}} \times \cancel{100} = \dfrac{20}{1} \times 2$

$\tt \longrightarrow \dfrac{20 \times 2}{1}$

$\tt \longrightarrow \dfrac{40}{1} = 40 \bf\%$

$\Huge\therefore$The loss percentage is 40$\bf\%$.
