Find the difference in profit:

Difference in profit = 15% - (-15%) = 30%

Difference in profit = Rs 360

Find 1%:

30% = Rs 360

1% = 360 ÷ 30 = Rs 12

Find 100%

1% = Rs 12

100% = 12 x 100 = Rs 1200

Answer: The cost price is Rs 1200

Answer 2

Answer:

1200

Step-by-step explanation:

let cp of the radio be 'x'

sp = (100 +15)x /100

115x/100

1.15x

it sold for 360 less

new sp , =1.15x

loss = 15%

= ( 100 - 15 )x / 100

= 85x/100

=0.85

0.85x = 1.15x -360

-0.30x= 360

x= 360 / 0.30

x= 36000/30

x=1200
