I wanted to purchase 10 chairs for the class room whose cost was Rs. 200 each. the trader offered me a discount if I were to purchase a set of 12 chairs. So I calculated that if I assume the normal price of 10 chairs then we can purchase 2 extra chairs which cost me only Rs. 80 each of two chairs at the cost price of 12 chairs after discount. What is the percentage discount?
Correct Answer: 10%
Explanation:
Price of 10 chairs = 10 x 200 = 2000
Price of 12 chairs (without discount)= 12 x 200 = 2400
Price of 12 chairs (with discount) = 10 x 200 + 2 x 80 = 2160
Therefore discount = 2400 - 2160 = 240 Hence discount % = (240 / 2400) x 100 = 10%
