S.P= RS 330, profit= 10%,C.P=Rs X , C.P = S.P -10% of C.P find C.P​

Answer 1

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

$\large\underline\mathbf\blue{Given :-}$

$\small\mathbf{•SP=Rs\:330}$

$\small\mathbf{•Profit\:=10\:٪}$

$\large\underline\mathbf\blue{To\:Find:-}$

$\small\mathbf{•CP(cost\:price)}$

$\large\underline\mathbf\purple{Solving:-}$

$\small\underline\mathbf{we\:know\:that:-}$

$\small\mathbf{•\:CP=SP-(10٪\:of\:CP)}$

$\small\mathbf{\pink{†{\:Let\:CP\:be\:x}}}$

$\small\underline\mathbf{Applying\:the\:formula:-}$

$\small\implies\mathbf{x=330-(\frac{10}{100}×x)}$

$\small\implies\mathbf{330=x-\frac{x}{10}}$

$\small\implies\mathbf{\frac{9x}{10}=330}$

$\small\implies\mathbf{x=\frac{330×10}{9}}$

$\small\therefore\mathbf{ x=366\:Rs}$

$\large\boxed{\green{\mathbf{CP = Rs\:366}}}$
