Download Solution PDFConcept used:
Effective discount = D1 + D2 - (D1.D2)/100
Here,
D1 = Discount 1
D2 = Discount 2
Calculation:
Statement I:
Effective discount = 10 + 10 - (10 × 10)/100
⇒ 20 - 1
⇒ 19%
Statement II:
Effective discount = 15 + 5 - (15 × 5)/100
⇒ 20 - 0.75
⇒ 19.25%
Statement III:
20% discount
So, from these three third discount scheme is the best
∴ The required answer is Option 3.
