hahaha....

here's something more closer to home...

3 friends rent a hotel room = RM30

each one came up with RM10

= RM10+10+10=RM30

it turns out, on that day, there was a special offer at the hotel

rent of hotel room = RM30-RM5 = RM25

so...rent of room is now RM25..leaving a balance of RM5

the girl at the hotel reception had to return the balance of RM5

to the 3 friends but dunno how to split the money...RM5 divide by 3 =???

after a while...she decides to return each of them RM1.

RM1+1+1=RM3

& the balance of RM2 is given as tips to the reception girl...

so....to summarize....rent of hotel room started as RM30...

each one of the 3 friends cough up RM10...

=RM10-RM1 (money returned by the reception)

=RM9 X 3(the 3 friends) = RM27

=RM27 + RM2 (the tip money to the reception gal) = RM29

now....where did the RM1 go???

=RM10-RM1 (money returned by the reception)

=RM9 X 3(the 3 friends) = RM27

=RM27 + RM2 (the tip money to the reception gal) = RM29

*pardon my translation....taken from a MY site....

 

The key lies in the fact that the money paid to the gal is not considered a net inflow, but an additional outflow in addition to the RM25 required.

 

The total outlay needed for Room + Tips is $25 and $2 respectively, and as such the total net outflow borne by 3 jokers = ($25 + $2 = $27, shared equally by 3 = $9 ea)

 

The accounting entry would be

 

Expense - RM30

Discount (Gain) on expense (RM5)

Net Expense - RM25

Additional Expense - RM2

Total Expense - RM27

 

Expense attributed from each user = 33.33% of $27 ~ RM9.

There's no link between the return of $5 (of which each person gets back $1 and the Hotel Reception $2) and your equation of: ($10-$1)x3 + $2 = $29

 

If you wanted to write the equation, it should be:

Each paid $10 so: $10 x 3 = $30

As $5 was returned to them, total sum now makes it $30 - $5 = $25

Making it easier to split the money, they each took $1 and had $2 to spare (which they gave the receptionist)

So they spent $25 + $2 = $27

 

Effectively, the equation will be $25 + $1 x3 + $2 = $30.

 

It's just how to play with the equations to make it seem as if $1 went missing

So they spent $25 + $2 = $27

 

Effectively, the equation will be $25 + $1 x3 + $2 = $30.

 

Yes that is correct. Each person paid RM 9 x 3 = RM 27

 

Out of which RM25 (room) + RM2 (gal) = cash outflow of RM27.

Same logic problems our primary 6 PSLE students faced.

 

Not the math number issues.....but purely understanding logic problem.

hehe...agreed....the numbers are fine...its the frigging "short story" wrapping around those numbers that is giving me the white hairs!

So complicated for what?

It's a simple thing.... the RM2 was double counted, that's all.
