Question
Mr. Karma started a Coaching classes and for that he
wanted to purchase 50 chairs for the classroom cost of which was Rs.200 each. The trader offered him a discount only if he purchases a set of 60 chairs. So he calculated that those 10 extra chairs are costing him only Rs. 80 each after the discount. What is the Percentage discount given by the shopkeeper?Solution
Price of 50 chairs = 50 × 200 = 10000 Price of 60 chairs (without discount) = 60 × 200 = 12000 Price of 60 chairs with discount = 50 × 200 + 10 × 80 = 10000 + 800 = 10800 ∴ Discount = 12000 – 10800 = 1200 Discount % = 1200/12000 ×100 = 10%
