This is a case of successive discounts.
Effective discount = -a -b + ab/100

Effective Discount = -20 - 20 + 400/100 = -36%

Final cost = 100 - 36 = 64% of the initial cost
(Make sure you answer what is asked. You are not asked the total discount, but the final cost after discount)

Correct Option: E

Hi
another way to look at it..
there is a 20% discount on 100 and on the reduced price there is another 20%...
so TOTAL dicount has to be < 20+20..
so our answer has > 100 - (20+20) or >60..
ONLY E fits in

If the price of the jacket is 100, and it is marked down by 20% twice or charged 80% of the price first and 80% of the price of reduced price, the final price is :-

100*80*80/10000= 64

64% is the final price of old price.

E is the answer

if the initial price is 100, and then the marked 20% first time the price will be 80
and second time another 20% down, will lead to 80-16 = 64%

start from 100. 20% decrease means the new price is 80.Another 20% decrease from 80 means a decrease of 16. The new price is 64.
Now this represents a 36% decrease, but that is not what the question asks! The answer B plays on this trick on those who dont read the question. It asks what % the new price of the old price . This is 64/100*100 => 64%.
