A common practice in some enterprises is to not advise employees of the full salary range for their position. The policy is to often give the lower end of the salary range for their position, a percentage which represents where they sit within the range, their salary but not the figure representing the upper end of the salary range.
As a people leader in an enterprise this seems a little myopic as anyone who's a little smarter at maths than me should have no problem calculating the upper figure.
So in a vein similar to this question. If I have a range of two numbers where
l is the lower number in the range
v is value within the range
p represents the percentage within that range
u is the unknown upper number in the range
If l = 10, v = 15 and p = 50% how do I calculate u?
Hint
Subtracting $10$ from $l$ and $v$ gives $0$ and $15$.
Now $0$ is $0 \%$ of the range, and $5$ is $50 \%$ of the range. You can first find that $1 \%$ of the range is $\frac{5}{50}$, so the maximum value of the range at $100 \%$ will be $\frac{5}{50} \cdot 100$.
Now you just need to add $10$ back.
