Answer 1

the cost price of each radio would be Rs.2000

Answer 2

hey mate!!!!!!!!!!!!!!

case 1

cp=rs1000

loss%=20%

sp= (100-L%/100)cp

  = (100-20/100)1000

  = (80/100)1000

   =rs 800

as both the sp are same so,

sp of 1 radio =sp of another radio=rs800

case 2

sp=rs800

p%=20%

cp= (100/100+p%)sp

   = (100/100+20)800

   =(100/120)800

   =rs 666.6
