While selling a watch a shopkeeper gives a discount of 5%. If he gives a discount of 7%, he earns Rs. 15 less as profit. What is the marked price of the watch?
Correct Answer: None of these
Explanation:
Let the marked price be Rs. x
Then, (7% of x ) - 15 = 5% of x
⇒ 7x / 100 - 5x / 100 = 15
∴ x = 750
