Answer:
Marked price is Rs. 53333.33 and the cost price is Rs. 42333.33.
Step-by-step explanation:
Let Rs. x and Rs. y are the cost price and marked price of the mobile set respectively.
Now, the man has a loss of Rs. 8000 after giving a 15% discount on the marked price.
Therefore, 15% of y is 8000 i.e. 
⇒ y = Rs. 53333.33
Now, the man gained Rs. 3000 by selling the mobile set allowing 15% discount on the marked price.
Therefore, the mobile set has the cost price = x = Rs. [(53333.33 - 8000) - 3000] = Rs. 42333.33 (Answer)
