x percent of y = xy/100leumas wrote:If x percent of y is equal to y percent less than z, what is y in terms of x and z?
y percent less than z = z - y percent of z = z - yz/100
Hence, xy/100 = z - yz/100
----> xy = 100z - yz
----> xy + yz = 100z
----> y(x + z) = 100z
----> y = 100z/(x + z)
The correct answer is E.
