The cost price

Taken :

To find the cost price use this formula -:

$\boxed{\sf{C.P.=\dfrac{100\%}{100\%-L\%}\times\:S.P.}}$

Where,

C.P. = Cost price

L% = Loss percentage

S.P. = Selling price

Solution :

$:\implies\sf{C.P.=\dfrac{100\%}{100\%-10\%}\times90}$

$:\implies\sf{C.P.=\dfrac{100\%}{\cancel{90}\%}\times\cancel{90}}$

$:\implies\sf{C.P.=100\%\times1}$

$:\implies\sf{C.P.=Rs.100}$

So , the cost price is ₹100 .
