Question

While selling a book for Rs 600 a seller makes a profit of Rs 100. Find out his profit%? * 25 20 15 10​

Answer 1

${\large{\bf{\red{\underline{Given :}}}}}$

• Selling price of book = Rs 600.
• Profit = Rs 100.

${\large{\bf{\blue{\underline{To Find}}}}}$

• Find profit %.

${\large{\bf{\orange{\underline{Solution }:-}}}}$

Formula for profit % :

${\blue{\boxed{\pink{\mathfrak{Profit \: percent = \frac{profit}{cost \: price} \times 100 }}}}}$

Than,

• Profit = 100
• Cost price = 600

Next,

${\mapsto{\bf{ \frac{profit}{cost \: price} \times 100}}}$

${\mapsto{\bf{ \frac{100}{600} \times 100}}}$

${\mapsto{\bf{ {\cancel\frac{10000}{600} }}}}$

${\blue{\mapsto{\orange{\boxed{\bf{16.67 \: percent}}}}}}$

So,

${\green{\boxed{\underline{\bf{Profit \: percent = 16.67 \: percent}}}}}$

Answer 2

${\large{\bf{\red{\underline{\underline{Given :}}}}}}$

• Selling price = Rs 600
• Profit = Rs 100

${\large{\bf{\blue{\underline{\underline{To Find :}}}}}}$

• Find the profit %.

${\large{\bf{\orange{\underline{\underline{Solution :}}}}}}</p><p>$

Formula to use :

${\blue{\boxed{\pink{\bf{Profit \: percent = \frac{profit}{cost \: price} \times 100}}}}}$

Than,

• Profit = 100
• Cost price = 600 - 100 = Rs 500

Next,

${\mapsto{\bf{ \frac{profit}{cost \: price} \times 100 }}}$

${\mapsto{\bf{ \frac{100}{500} \times 100 }}}$

${\mapsto{\bf{ {\cancel\frac{10000}{500} }}}}$

${\blue{\dashrightarrow{\red{\boxed{\bf{20 \: percent }}}}}}$

So,

The profit % of book is 20%.
