C Correct answer
Explanation

Selling Price = Cost Price * (1 - loss%). 20000 = CP * (1 - 0.20) = CP * 0.8. CP = 20000 / 0.8 = 25000.

AI explanation

Using the cost price formula, Cost Price equals Selling Price multiplied by 100 divided by the quantity 100 minus the loss percentage. Substituting the given values gives 20000 times 100 divided by 80. This calculates to Rs. 25000 as the cost price.
