Answer 2

• GIVEN:-

CP = Rs. 17.50

Profit % = 18%

• To Find:-

The SP.

• SOLUTION:-

We know that,

$\large\boxed{\tt{SP =\huge(\large 1+\frac{Profit \%}{100}\huge)\large\times\:CP}}$

According to the question,

$\large\Longrightarrow{\tt{SP =\huge (1+\frac{Profit \%}{100})\large\times\:CP}}$

$\large\Longrightarrow{\tt{SP =\huge( 1+\frac{18}{100})\large\times\:17.50}}$

After cancellation,

$\large\Longrightarrow{\tt{SP =\huge 1+\frac{9}{50}\large\times17.50}}$

$\large\Longrightarrow{\tt{SP = \huge\frac{50+9}{50}\large\times17.50}}$

$\large\boxed{\tt{SP = Rs. 20.65 }}$

• Now let's verify it:-

We know,

Profit = SP - CP

Profit = Rs. (20.65 - 17.50)

Profit = Rs. 3.15

Now,

$\large\Longrightarrow{\tt{Profit \% =\huge \frac{Profit}{CP}\large\times100}}$

$\large\Longrightarrow{\tt{18\%= \huge\frac{3.15}{17.50}\large\times100}}$

$\large\Longrightarrow{\tt{18\% = 0.18\times100}}$

$\large\Longrightarrow{\tt{18\% = 18\% }}$

$\large\boxed{\tt{LHS=RHS}}$

$\huge\purple\therefore\boxed{\tt{\purple{SP = Rs\:\:20.65 }}}$
