Answer 2

Answer:

15360

Step-by-step explanation:

Let the cost price of her fridge be x

if she sold it at the loss of 20%

The selling price of the fridge would be = x - 20/100 of x

= 4x/5

It is given to us that s.p is 10240

or 4x/5 = 10240

x = 2560 × 5

x = 12800

Hence if she sells it at a profit of 20%

she would sell it at 12800 + 20/100 of 12800

= 12800 + 2560

= 15360
