Question

plz solve it, the percentage profit earned by selling an article for rupees...​

Answer 1

now we should take as price of product as x

and profit perctage as x%

so the

x+x%=1920. (1)

x-x%=1280. (2)

now add both (1)+(2)

x+x%+x-x%=1280+1920

2x=3200

x=1600

now the product sold at 25%profit

means 1600+25%

=2000

the product price is 2000
