hi everyone.. i have a simple but puzzling problem that i came across. just read the example:

say you have high-low-mid situation for say expectations for products..

so, you ll have :

Low:10

mid:20

high:30

total=60

Now, say we want to check what the 30% would be of that total (simple answer..) =18

the problem begins now..:

say we assign some percentages for this low-mid-high averaging to 30%..just to check

so, say aagain that we assign further that:

low: 10% of the 10 above (=1)

mid:30% of the 20 (=6)

high:50% of 30..(=15)

the average of these percentages is 30% but the result is22!!..

i can see that the last 30% does not represent the 30% of the total directly...but then again..it s 30%...well once again i am puzzled to explain it can u please tell me the reason?
