Dears,

Hint: Administrator feel free to change my post Title “as I didn’t find good Title describing it”

Kindly support to do the following:

I’ve several Major roads and for each Road we calculate population after each 1 KM in points called “Count point_1, Count point_2, etc”, we have found that population is randomly distributed

Consequently, we need to calculate for each Road
• 90% Population: Provides Count point_#Number before which 90% of the total Population are located.

Sample Data:

<TABLE style="WIDTH: 785pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=1049><COLGROUP><COL style="WIDTH: 69pt; mso-width-source: userset; mso-width-alt: 3364" width=92><COL style="WIDTH: 71pt;

Dear Friend, Firstly how to calculate 90% for each road :confused:

I suppose shg has the following formula in M2, copied down:

=SUM(B2:K2)*90%

Also...

Define BigNum (by means of Insert|Name|Define or Formulas|Name Manager) as referring to:

=9.99999999999999E+307

Now invoke:

N2, control+shift+enter, not just enter, and copy down:
Code: 
=INDEX($B$1:$K$1,MATCH(BigNum,IF(SUBTOTAL(9,OFFSET(B2,0,0,1,
    COLUMN($B$1:$K$1)-COLUMN($B$1)+1))/SUM($B2:$K2)<=0.9,1,"#")))

If so desired, the SUM bit in the denominator can be replaced with M2.

Let A1:K6 house the data you provided, including the headers in A1:K1.

M2, just enter:

=SUM(B2:K2)*90%

N2, control+shift+enter, not just enter, and copy down:

=INDEX($B$1:$K$1,MATCH(9.99999999999999E+307,IF(SUBTOTAL(9,OFFSET(B2,0,0,1,COLUMN($B$1:$K$1)-COLUMN($B$1)+1))/SUM($B2:$K2)<=0.9,1,"#")))

Note 1. Control+shift enter means: Press the control and shift keys down while you hit enter.

Note 2. If so desired, define BigNum as referring to 9.99999999999999E+307 and replace this number with BigNum in the formula.

Note 3. The formula has a SUM term in the denominator. If so desired, you replace that bit with M2.

Dear Aladin,

Thanks a lot..we are acheiveing Good progress;
Could you please explain in details the meaning/ Description of below function:

=INDEX($B$1:$K$1,MATCH(9.99999999999999E+307,IF(SUBTOTAL(9,OFFSET(B2,0,0,1,COLUMN($B$1:$K$1)-COLUMN($B$1)+1))/SUM($B2:$K2)<=0.9,1,"#")))

Yoy are welcome. Did we miss something?

Could you please explain in details the meaning/ Description of below function:

=INDEX($B$1:$K$1,MATCH(9.99999999999999E+307,IF(SUBTOTAL(9,OFFSET(B2,0,0,1,COLUMN($B$1:$K$1)-COLUMN($B$1)+1))/SUM($B2:$K2)<=0.9,1,"#")))
Click to expand...

The SUBTOTAL expression creates a set of cumulative totals from B2, B2:C2, B2:D2,...,B2:K2. This proggressive range construction is due to the last term within the OFFSET bit.

The IF bit examines whether these subtotals divided by the total of B2:K2 (effectively, percentage values) are less than or equal to 0.9 and produces a 1 for a hit and a # for a no-hit. The intermediate result is an array constant of 1's and #'s like in:

{1,1,1,#,#,...}

The surrounding LOOKUP with the big number as look up value lands on the last numeric value and picks out the cooresponding value from B1:K1 which houses count points.
