Answer»

Answer:

10000

Step-by-step explanation:

Let US CONSIDER that the cost price of sound system is - "X" RS

Now

also cost price of LCD is 28000

=> So

profit on LCD - loss on sound SYSTEM = 6000

means

=> 28000×25/100-10x/100 = 6000

=> 7000- 10x/100 = 6000

=> 700000-10x = 600000

=> 10x = 100000

=> x = 10000

cost price of sound system is 10000
