Dear all
Greetings!
B, C, D, E, F, G, H and I, have a percentage values in left side of attached table. The A is number of days which is common for all B to I.
The right side table in yellow colored is a result of day which is 10% and 90% of every stage.
The yellow colored result is calculated manually. For example: If I need to find a 10% and 90% values at A for B, I have used following formula: "A7+(A8-A7)/(SUM (B7:B8)/10)/100" and "A24+(A25-A24)/(SUM(B24:B25)/90)/100" to get the actual day from A.
I have use similar formula to all stage. But doing manually is a very lengthy process. My question is: Can anyone know how to I fixed the formula in excel sheets? And it is easy to get result in same time when I put values in B3 to I31.
