Today, all the items in a store are 30% discounted. Currently, the kitchen items are 20% discounted. Based on this 20% discounted price, how much is the discount today?
I agree, language in this problem is not very clear, however,
my answer would be 12.5%
based on 20% discount
(0.8 - 0.7) / 0.8 = 12.5%
Oh you calculated on the basis of total discount being 30%, and one discount being 20%, what was the other discount???
So after 20% discount, 0.8 (1-x) = 0.7
=> 1-x = .7/.8 = 0.875 => x = .125 = 12.5%????
I didn't get the very simplistic calculation that you did. Tell me the secret
