To find the original price (OP) of the wristwatch, we can use the formula for the selling price (SP) after applying a discount:

$$
SP = OP - D
$$

where $$ D $$ is the discount amount. The discount can also be expressed in terms of the original price:

$$
D = \frac{D R}{100} \times OP
$$

Given that the discount rate (DR) is $$ 20\% $$ and the selling price (SP) is $$ 2500 $$, we can substitute these values into the equations.

1. First, express the discount in terms of the original price:

$$
D = \frac{20}{100} \times OP = 0.2 \times OP
$$

2. Substitute $$ D $$ into the selling price equation:

$$
SP = OP - D
$$
$$
2500 = OP - 0.2 \times OP
$$

3. Combine like terms:

$$
2500 = 0.8 \times OP
$$

4. Now, solve for the original price (OP):

$$
OP = \frac{2500}{0.8}
$$
$$
OP = 3125
$$

Thus, the original price of the wristwatch was **Php 3125.00**.
The original price of the wristwatch was Php 3125.00.
