Detailed Solution

Concept: The formulae related to percentage change in the value of an entity and absolute change in the value of the entity. This question can be easily solved using this concept.
Suppose the original price = x
Now we will be finding 80 percent of the original price that is x.
So, the 80% of x = 40,000
Now, x= 50,000
(50,000 – 40,000) =10,000
Hence, the correct option is 1) 10000
