PERCENTAGES
It is given that 5% increase in X always means 3% increase in Y and 5% increase in Y always implies 2.5% increase in Z. Relationship between X and Z could be
-
- 1.05 X = 1.025 Z
- 0.5 X = 0.25 Z
- 25X = 7.5 Z
-
250X = 213Z
Solution
X * (5/100) = Y * (3/100)
X / Y = 3 / 5
Y * (5/100) = Z * (2.5/100)
Y / Z = 1 / 2
X : Y =3 : 5
Y : Z = 1 : 2
X : Y : Z = 3 : 5 : 10
X / Z = 3 / 10
25 X = 7.5 Z
