Answer 1

Answer:

Sp=230

Profit=15%

$x \times \frac{115}{100} = 230$

$x = 200$

$x = \frac{100}{110} = 200$

$x = \frac{200 \times 110}{100}$

$x = 220$

Answer 2

$\huge{\boxed{\red{\bf{Question:-}}}}$

A calculator is sold for ₹230 at a profit of 15%. What is its Cost Price?

At what price must it be sold to make a profit of 10%?

$\huge{\boxed{\red{\bf{Solution:-}}}}$

Let the Cost Price (C.P.) be ₹ ${x}$

Selling price (S.P.)= ₹230

Profit% = 15%

Profit amount = $\frac{15}{100}×{x}$

= ₹ $\frac{3x}{20}$

ACCORDING TO THE QUESTION:-

${x}+\frac{3x}{20}={230}$

$\frac{20x}{20}+\frac{3x}{20}={230}$

$\frac{(20x+3x)}{20}={230}$

$\frac{23x}{20}={230}$

${x}=\frac{(230×20)}{23}$

${x}= ₹ {200}$

Now, to make a profit of 10%:-

Profit amount = $\frac{10}{100}×{200}$

= ₹ ${20}$

S.P. =₹ (200+20)

= ₹220

$\huge{\boxed{\red{\bf{Answer:-}}}}$

The Cost Price of the calculator is ₹200.

It must be sold at ₹220 to make a profit of 10%.
