Hi everyone. This is my first post here. Ty for having this forum.

I have 3 given numbers
Min. 50
User Defined 69
Max. 105

I need to find out what's the percentage of the 69.
Once the percentage has been determined I need to use that percentage in a different number grouping to determine the User Defined number will be.
Min. 75
User Defined X = % from first group.
Max 185
How can I find the user defined value, using the same percentage from the first grouping.

I'm sorry, but I have no idea what this means...? :shock:

Please reply with the full and exact text of the exercise, the complete instructions, and a clear listing of what you've tried so far. Thank you! ;)
 
A percentage is just a ratio multiplied by 100 (the 100 because percent means per 100). So, what you want is the ratio of your user defined X's (one of which is given as 69) to be the same in both cases. The problem is, you don't say which ratio (percentage). Is it with the minimum? The maximum? The average of the minimum and maximum? Just what percentage are you talking about?

This is a real life question. Not in a book, if that really makes a difference.
I trying to work on a chart that has Minimum Stock, Current Stock, Maximum Stock. The Current Stock cannot go below the MIN or above the MAX.

A = Minimum Stock
B = Current Stock
C = Maximum Stock
D = Current %

A = 50
B = 75
C = 105
D = Current %

Step 1
(B-A)=25
Step 2
(C-A)=55
Step 3
25/55=.4545
Step 4
.4545*100=%45.45

Now lets say I want to keep that same 45.45% for other groupings.
A = 16.75
B = ?
C = 90.30
How can I solve for B by using the 45.45%.

Let Mid be the stock on hand so that what you said, as I understand it, is that you want
A = (Mid - Min) / (Max - Min)
to be constant across different stocks. From the first example, A = 0.4545 or 45.45%. Thus
Mid = A (Max - Min) + Min
Thus for your second example
Mid = 0.4545 * 73.55 + 16.75 = 50.17848

To check:
Step 1
(B-A)=33.42848
Step 2
(C-A)=73.55
Step 3
33.42848/73.55=.4545
