Excel random number (based on another cell)
Posted on 2013-12-10
I need assistance with deriving a random number which range is determined by the value of another cell.
Usually, for a random number generation, I may chose the following formula:
... which, as you know, generates any number between 1 and 20.
Now, here's what I need to achieve instead. Based on another cell value, derive a random number that is within a 30% range (up or down). For example, let's say I have the following values in the below cell range:
Cell A1 = 10
Cell B1 = random number should be between 7 or 13 (30% of 10 = 3... thus, 10 - 3 or 10 + 3)
Cell A2 = 90
Cell B2 = random number should be between 63 and 117 (30% of 90 = 27... up or down)
Does anyone know how to generate the random number function for this concept?
