28%

40%

64.8%

70%

72%


Let the initial price before any sales be 100. Thus price after first 10% discount = 90. After second 10% discount = 81. After additional 20% discount = 64.8.

Thus required percentage = \(\frac{64.8}{90}*100\) = 72 %

E.

original price = 100
day 1 discount = 10%,price = 100-10 =90
day 2 discount = 10%,price = 90-9=81
day 3 discount = 20%,price = 81-16.2= 64.8
which is 64.8/90 *100 of the sale price on day 1= ~72%

Let initial price be 1000

Price in day 1 after 10% discount = 900

Price in day 2 after 10% discount = 810

Price in day 3 after 20% discount = 648

So, Price in day 3 as percentage of the sale price on day 1 will be = 648/900*100 => 72%

Answer will definitely be (E)
