Answers
Given : A retailer gives three successive discounts of 10%, 15%, and 10% on the marked price of an article of Rs.1000 and also giving another option of availing two successive discounts of 20% and 10%.
To Find : the difference in the selling price under these two options after discount,
Solution:
A retailer gives three successive discounts of 10%, 15%, and 10% on the marked price of an article of Rs.1000
Selling Price after 3 Successive discounts = 1000 * ( 1 - 10/100)(1 - 15/100)(1 - 10/100)
= 1000 (0.9)(0.85)(0.9)
= 810 (0.85)
= 688.5 Rs
Selling Price after two successive discounts of 20% and 10%.
= 1000 ( 1 - 20/100) ( 1 - 10/100)
= 1000 (0.8)(0.9)
= 720 Rs
difference in the selling price under these two options after discount
= 720 - 688.5
= Rs 31.5
difference in the selling price under these two options after discount, = Rs 31.5
