A catalogue advertises successive discounts of 15% and 10% on tape recorders. What is the net price of a Rs. 200 tape recorder?
💡
Step-by-Step Explanation & Concept Rationale
Apply the first discount (15%):
Discount amount = \(200 \times 0.15 = \text{Rs. 30}\)
Price after 1st discount = \(200 - 30 = \text{Rs. 170}\)
Apply the second discount (10%) to the reduced price:
Discount amount = \(170 \times 0.10 = \text{Rs. 17}\)
Final net price = \(170 - 17 = \mathbf{\text{Rs. 153}}\)
Discount amount = \(200 \times 0.15 = \text{Rs. 30}\)
Price after 1st discount = \(200 - 30 = \text{Rs. 170}\)
Apply the second discount (10%) to the reduced price:
Discount amount = \(170 \times 0.10 = \text{Rs. 17}\)
Final net price = \(170 - 17 = \mathbf{\text{Rs. 153}}\)
