Question

a trader marks his goods 20% above the cost price he sells them at a discount of 20% if the cost price is rupees 1100 what is his gain or loss percent

Answer 1

let the cost price be x

so the cost price will be 20x/100 = 1100   (20 %/100%)

20x=100*1100

20x=110000

x=110000/20

x=5500 rupees

then find 20% of 5500 and subract it from 5500 which as follows:

20/100*5500

=1100

this shows that it neither profit nor loss but the same price

Answer 2

Answer:

sp=528

Loss percent =4 percent
