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 ?
-
- Rs. 697.50
- Rs. 712.50
- Rs. 787.50
- None of these
Correct Option: D
Let the marked price be Rs. x
Then, (7% of x ) - 15 = 5% of x
⇒ 7x / 100 - 5x / 100 = 15
∴ x = 750
