It is not a very tough question as it has all the information's required to find the necessary answer. It is already given that 82 1/2% of a certain number is 330. It is required to find the unknown number. So we have to create an equation with a single unknown number.
Let us assume the number to be = x
then we can easily write the equation as given below.
82 1/2% x = 330
(165/4)%x = 330
(165/400)x = 330
x = (330 * 400)/165
= 2 * 400
= 800
So the unknown number is 800.
