If the same article is marked up by 20% and sold after a discount of Rs. 280, would fetch 610 less than the previous transaction. If another article B whose cost price is Rs. 1700 more than the article A is marked up by 10% and the discount given on article B was Rs. 690 then find the selling price of article B?
