Cost price of refrigerator $$=Rs. 12,000$$
Selling price of refrigerator $$=Rs. 13,500$$
Since, S.P> C.P, therefore here is profit
$$\therefore$$ Profit =S.P-C.P$$=13500-12000=Rs.1,500$$
Now Profit%$$=\cfrac{Profit}{C.P}\times 100=\cfrac{1500}{12000}\times 100=12.5$$%
Therefore, Profit $$=Rs.1500$$ and Profit %$$=12.5$$%
