Answer:
The original cost of Car at the time of purchased = 20500 unit
Step-by-step explanation:
According to question ,
Mr. Kork selling cost of his Car = 8400 unit
And Selling cost is 200 more than two fifths of the purchased cost of Car .

So, AS per question
200 +
× x = 8400
Or,
× x = 8400 - 200
i.e
× x = 8200
