A Correct answer
Explanation

Let the price be 100 rupees. Then, after 20% discount, price = 80 rupees Now, again 10% discount, price = 80 - (80*10/100) = 72 rupees Now, again 10% discount, price=72 - (72*10/100) = 64.8 rupees So, total discount = 35.2 rupees Answer = 35.2% discount Hence, this option is correct.
