Answer 2

Answer:

The selling price of watch = Rs.6500

Step-by-step explanation:

Given data

A shopkeeper initially marked an electronic watch to get 30% profit

and gave a discount of 20%

⇒ after that he got a profit of Rs.250    

Let x be the cost price then he marked at a price so that he get 30% profit

⇒ profit of 30% on x = $\frac{30}{100} (x)$  = $\frac{3x}{10}$  

⇒ the marked price = $x + \frac{3x}{10}$ = $\frac{10x+3x}{10}$ = $\frac{13x}{10}$  

⇒ he gave 20% discount on marked price = $\frac{20}{100} (\frac{13x}{10} )$ = $\frac{13x}{50}$  

⇒ the selling price = marked price - discount

                               = $\frac{13x}{10} -$ $\frac{13x}{50}$  = $\frac{65x - 13x}{50}$  = $\frac{52x}{50}$  

⇒ profit = selling price - cost price  = $\frac{52x}{50} - x$  

                                                          =  $\frac{52x-50x}{50}$ = $\frac{2x}{50}$ = $\frac{x}{25}$  

⇒  which is equals to 250

⇒  $\frac{x}{25} = 250$  ⇒  x = 6250

⇒  selling price = $\frac{52x}{50}$ = $\frac{52(6250)}{50}$  = 52(125) = 6500
