Given: On selling a mobile for RS 750 shopkeeper losses 10%.

To do: Find for what amount should he sells it to gain 5%.


Solution: 


Selling price  =  750 ₹

Loss   =   10 %

So, the selling price is 90% of cost price.

90 %  of CP    =  750₹

               CP    =  750 $\times \frac{100}{ 90}$

                         = $\frac{ 75000}{ 90}$

                CP   =  833.33 ₹

To gain 5% on cost price, he should sell for 105%

       105 % of CP  =  833.33 $\times \frac{105}{ 100}$

                                =   $\frac{87500}{100}$  

                                =  875 ₹

Therefore to gain 5% on cost price, he should sell for 875 ₹
