Detailed Solution

Concep- By designating a variable for the microwave oven's initial purchase price, we may begin to solve the problem. The price Samant paid is then determined by deducting 10% from the microwave's original purchase price of 100%. The selling price of the microwave is then calculated by adding to the cost at which it was purchased. Next, we determine the profit he makes from the Question Image, we compute the profit %.
Let's assume original price of the microwave oven = Rs. 100
So, buying price for Samant = Rs. 90
Profit %=30%= p×100  Costprice   
30%= p×100 90  
30×90100=p  
 profit =27  
 Selling price =90+27=117Rs  
 Profit =117−100=17Rs  
 profit %= 17×100 100 =17%  
Hence, the correct answer is option 1.
