Question

find a single discount equivalent to three successive discounts 20%,5% and 1%​

Answer 1

Answer:

Single disocunt combining all three discount is 31.60%

Step-by-step explanation:

Let selling price be ₹100

First Discount 5% = 5 × 100/100 = ₹5

Price after first discount = ₹100 – 5 = ₹95

Second discount 10% on price after first discount = 10/100 × 95 = ₹9.50

Price after second discount = ₹95 – 9.50 = ₹85.50

Third discount 20% on price after second discount = 20/100 × 85.50 = ₹17.10

Price after third discount = ₹85.50 – ₹17.10 = ₹68.40

Single disocunt combining all three discount will be = 100 — 68.40 = ₹31.60

As selling price taken was ₹100 therefore discount will be 31.60%
