The profit earned by selling a phone for ₹18000 is same as the loss incussed after selling it for ₹16,800.What is the cost price of the phone?

dude split the difference and divide by 2 add or subtract to major or minor

let loss/gain =x rupees cp=18000-x (1) cp=16800+x. (2) (1)=(2) 16800+x=18000-x 2x=1200 x= 600 cp=18000-600= 17400

2x= 18000-16800 = 1200 therefore X= 600. hence, we know that, cost price = selling price _ profit (or) =selling price + loss =18000_600=17400 (or) =16800+600=17400.
