Step-by-Step Solution

To determine the original selling price of the watch, we can use the concept of percentage discounts.

1. Understand the relationship:

   • A 25% discount means Vanita paid 75% of the original selling price.

   • Let the original selling price be x.

2. Set up the equation:

   • 75% of x = Rs. 780

   • 0.75 * x = 780

3. Solve for x:

   • x = 780 / 0.75

   • x = 1040

The original selling price of the watch was Rs. 1040.
