Question

if the selling price is 3600 rupees and cost price is 4150 rupees so what is the loss percent of it

Answer 1

Cp- sp= 550
(550/4150)×100
13.25%

Answer 2

Given 
Selling Price = 3600
Cost price = 4150
Loss = cost price - selling price
        = 4150 - 3600
        = 550
therefore,
Loss percent = loss*100/cost price
                      = 550*100/4150
                      = 55000/4150
                      = 13.25
