let the marked price of the watch be MP. So the selling price = .85 MP
Profit = .85 MP - CP
If the discount = 20%, selling price = .8 MP
Profit = .8 MP - CP
But (.85MP - CP) - (.8MP - CP) = 51
So, .05 MP = 51
or MP = 1020

To solve this problem, let's assume the original price of the watch is 'x' rupees.
Given that the shopkeeper gives a discount of 15%, which means he sells the watch for 85% of its original price. So, the selling price in this case would be 0.85x rupees.
According to the question, if the shopkeeper gives a discount of 20%, he earns Rs. 51 less as profit. This means that the selling price with a 20% discount would be 51 rupees less than the selling price with a 15% discount.
Let's calculate the selling price with a 20% discount:
Selling price with a 20% discount = (100% - 20%) * x = 0.8x rupees
Now, we know that the selling price with a 20% discount is 51 rupees less than the selling price with a 15% discount. So, we can write the equation:
0.85x - 0.8x = 51
Simplifying the equation, we get:
0.05x = 51
Dividing both sides by 0.05, we find:
x = 51 / 0.05 = 1020
Therefore, the original price of the watch is Rs. 1020.
So, the correct answer is option 'D' Rs. 1,020.

Therefore, the original price of the watch is Rs. 1020.
So, the correct answer is option 'D' Rs. 1,020.
