A shopkeeper gives a discount of ₹ 12.50 on an article which costs ₹ 50. What is the selling price of each article?
(Round off the selling price of 11 articles to the nearest 10's).
Selling Price \(= ₹ ( 50 - 12.5) = ₹ 37.5\)
Selling price of 11 articles \(= 11\times 37.5 = ₹ 412.5\)
412.50 rounded off to the nearest tens is 410.
