Answer 1

Answer:

12%

Step-by-step explanation

Selling price=3120 rupees

loss percent=4%

Cost Price=( SP * 100 ) / ( 100 – percentage loss )

                 =  ( 3120*100)/(100-4%)

                 =₹3250

Sp  > Cp. So in second case

Gain=3640-3250= 390 rupees

Gain percent=390/3250*100

                      =12%

Answer 2

Answer:

12% profit

Step-by-step explanation:

sold price= ₹3120

loss percent=4%

let actual price be x

$\frac{x-3120}{x} =\frac{4}{100} \\96x=312000\\x=3250$

actual cost= ₹3250

now if it is sold for ₹3640

percentage profit   $\frac{3640-3250}{3250} *100=12$

12% is the profit
