Answer 1

Answer:

The cost price of the DVD player is 18000 Rs

Step-by-step explanation:

Given : Selling price of DVD player = 14400 Rs

             Loss = 20 %

Solution : The price includes loss 20 %

∴ The original cost is 100% -20% = 80%

So 80% cost = 14400 Rs

∴ 100% cost = 14400 x 100/80

                   = 18000 Rs

∴ The cost price of the DVD player is 18000 Rs

Answer 2

Step-by-step explanation:

sp of dvd player is 14400

loss is 20%

CP=100/100-loss%×sp

100/100-20×14400

100/80×14400=18000

you can check your answer,

cp is 18000,so is 14400

loss =sp-cp

18000-14400=3600

loss%=loss/cp×100

3600/18000×100=20%
