profit of Rs. 6,000 by selling both articles. If the cost
price of the LCD screen was Rs. 28,000. Find the
cost price of the sound system.

Answer 1

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
