'Simple' puzzle ...help please!
Hi,
I am having problems working out this percentage problem, which I'm
sure is really very simple.
Five partners receive shares in the following splits: 15%, 15%, 15%,
27.5%, 27.5%
The partnership wants to introduce a new partner and give him a share
that will be equal to the 15% guys new split.
All the existing partners must give a proportionately equal share of
their existing splits to accomodate the new partner.
What will be the new splits?
Hope you can help ..I'd love to see the method too if you don't mind
Thanks,
Jenny

Add the 6th partner, giving 115% in total. Then pro-rate all 6
shareholdings down to 100 / 115ths.
BTW, accommodate has two "m"s :-)))

Think in terms of a basic share and an enhanced share.
15% is a basic share, 27.5 is an enhanced share (enhancement is 11/6)
let y (in %) be the new basic share, in the new arrangement the shares are:
y + y + y + y + 11y/6 + 11y/6 and that has to be = 100 (in %)
so 4y + 22y/6 = 100
solve for y

Thanks Stan ...except it's three folks with equal shares of X and two
with equal shares of 1.833_X (not 1.5X)
Comes out X=13.04

You are 99% right -- and may I remark in passing that I love it when
a student corrects me. I know of no better proof that the student now
understands, which is the whole point of the exercise.
I say "99% right" because in fact the two shares are (11/6)X or
11X/6, not 1.833X. You should always solve exactly when possible, and
make a decimal approximation at the end, if at all.

That's an equation involving X, all right, :-) but I had in mind one
more like
4*X + 2*(11/6)*X = 1 <-- thanks to your correction
The solution:
(4 + 11/3)X = 1
(23/3)X = 1
X = 3/23 = about .1304 or 13.04%

That's an equation involving X, all right, :-) but I had in mind one
more like
4*X + 2*(11/6)*X = 1 <-- thanks to your correction
The solution:
(4 + 11/3)X = 1
(23/3)X = 1
X = 3/23 = about .1304 or 13.04%

Add the 6th partner, giving 115% in total. Then pro-rate all 6
shareholdings down to 100 / 115ths.
BTW, accommodate has two "m"s :-)))

Think in terms of a basic share and an enhanced share.
15% is a basic share, 27.5 is an enhanced share (enhancement is 11/6)
let y (in %) be the new basic share, in the new arrangement the shares are:
y + y + y + y + 11y/6 + 11y/6 and that has to be = 100 (in %)
so 4y + 22y/6 = 100
solve for y

In other words, X.

Can you write an equation involving X?

Re: 'Simple' puzzle ...help please!
Thanks Stan ...except it's three folks with equal shares of X and two
with equal shares of 1.833_X (not 1.5X)
Comes out X=13.04
Thanks,
Jenny

You are 99% right -- and may I remark in passing that I love it when
a student corrects me. I know of no better proof that the student now
understands, which is the whole point of the exercise.
I say "99% right" because in fact the two shares are (11/6)X or
11X/6, not 1.833X. You should always solve exactly when possible, and
make a decimal approximation at the end, if at all.
