You used 30% on all the numbers in your first calculation, not an AVERAGE of 30%.
You did the first one this way:
And the second one this way:
And therefore you will get two very different answers...
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 :
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 is 22!!..
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?
thanks.. i still got a little confused at the beginning but i figured out the whole thing with yr clue.
yes..indeed..that is how i first thought abt it,by using weight for each value.. but the wording trick is that since the first calculation represents 30% of the values...and then the second represents 30% of the values too...why not match!?i think i m getting confused again!lol
