Detailed Solution
Download Solution PDFFormula used:
Effective discount = D1% + D2% - (D1 × D2)/100
Discount = (free product × 100)/Total product
Calculation:
For case A :
Effective discount = D1% + D2% - (D1 × D2)/100
⇒ 10 + 15 - (10 × 15)/100 = 25 - 1.5
⇒ 23.5%
For case B:
Total discount = (free product × 100)/Total product
⇒ (2 × 100)/7 = 28.56%
∴ The correct option is 2.
