Let original price = 100
after 20% discount, price = 100 - (100×20/100) = 80
Then 30% discount, price = 80 - (80×30/100) = 56
total discount = 100 - 56 = 44
equivalent discount= 44/100 × 100 = 44%
after 20% discount, price = 100 - (100×20/100) = 80
Then 30% discount, price = 80 - (80×30/100) = 56
total discount = 100 - 56 = 44
equivalent discount= 44/100 × 100 = 44%
