1)What number is X% greater than Y?
2)X is what percent greater than Y?
3)X is what percent greater than Y percent of Z?
Let the number, N = X% of Y + Y = (XY/100 + Y)
(2) X is what percent greater than Y?
X = N% of Y + Y
X = NY/100 + Y
So, N = {(X - Y) * 100}/Y
(3) X is what percent greater than Y percent of Z?
X = N% of Y% of Z + Y% of Z
X = NYZ/(100 * 100) + YZ/100
10,000X = YZ(N + 100)
N = (10000X/YZ) - 100
