Answer 1

Answer:

Cost price = 240 rs.

Selling price = 300 rs.

Profit = 300-240= 60 rs.

Step-by-step explanation:

$profit\% = \frac{profit}{cost \: price} \times 100 \\ \\ = \frac{60}{240} \times 100 \\ \\ = \frac{600}{24} \\ \\ = 25\%$

Answer 2

➤ Given :-

Cost price :- ₹ 240

Selling price :- ₹ 300

➤ To Find :-

Profit percentage of the given sum...........

➤ Formula required :-

$\large \tt \dashrightarrow \orange{ \boxed{ \tt \gray{ \frac{Profit}{Cost \: price} \times 100 }}}$

➤ Solution :-

Profit :-

$\tt \longrightarrow300 - 240$

$\tt \longrightarrow \sf Rs \: \tt \: 60$

Now,

Profit percentage :-

$\tt \longrightarrow \dfrac{60}{240} \times 100$

$\tt \longrightarrow \cancel\dfrac{60}{240} \times 100 = \boxed { \tt\dfrac{1}{4} \times 100}$

$\tt \longrightarrow \dfrac{1 \times 100}{4} = \dfrac{100}{4}$

$\tt \longrightarrow \cancel \dfrac{100}{4} = 25 \bf\%$

$\Huge\therefore$The profit percentage of the watch is 25 $\bf\%$.
