Tarun got 30% concession on the labelled price of an article and sold it for Rs. 8750 with 25% profit on the price he bought. What was the labelled price ?

Cost Price =  $Rs.\frac{100}{125}\times 8750$ = Rs. 7000. Let the labelled price be Rs. x. 

Then,  $\frac{70}{100}*x=7000$  $\Rightarrow x=Rs.\frac{7000*100}{70}$ 

= Rs.10000
