Yes, There is no other pound.

You don’t ADD the £2 the bellboy kept, you SUBTRACT it to give you the £25 that they paid. If you want to get it to equal £30 you take the £27 that they paid and add the £3 that they got back.

Reply from SBArker51 /post/160381-maths-question#reply-3732916 OK different explanation the guys overpaid for the room by £2.00
It should have been £25 - they paid £27 the extra £2 was pocketed by the bellboy. You misdirected by added the £2.00 to get £29.00 rather than subtract it.
Their is no missing money!

Reply from piinkladiix0 /post/160381-maths-question#reply-3732912 [quote SBArker51]That should be in 6 years Rebecca is 18 - mum is 54 but anayway the original answer of 12 stands correct!

Rebecca=x
Mum =y
Y=4x

also Y+6=3(x+6)

therfore 4x+6=3(x+6)

(4x+6)/3 = X=6

(4/3)x+2=x+6

(4/3)x=x+4

(1/3)x=4
x=12

Simple![/quote]

Took me a while to figure it out, but that is indeed correct. =)

Reply from SBArker51 /post/160381-maths-question#reply-3732898 Sending £5 will the bellboy and retaing £25.00 means at that stage each person had ttechnically paid £8.3333(recurring) + £1.00 returned to them means each paid

9.33×3=£27.99 (rounded to 28.00) + £2.00 to the bellboy

Well done though I had to think for a second!

Reply from Bex /post/160381-maths-question#reply-3732889 Here’s one for you…

3 men go into a motel. the man behind the desk said the room is £30 - so each man paid £10 and went to the room.

A while later the man behind the desk realized the room was only £25 so he sent the bellboy to the 3 guys’ room with £5.

On the way the bellboy couldn’t figure out how to split £5 evenly between 3 men, so he gave each man a £1 and kept the other £2 for himself.

This meant that the 3 men each paid £9 for the room, which is a total of £27, add the £2 that the bellboy kept = £29.

Where is the other pound?

Let me know if you need the answer.

Reply from Anonymous /post/160381-maths-question#reply-3732861 rebbecca=r
mum=m

r=4m (1)
r+6=3m (2)
(1)-(2)
6=m
substitute into (1)
r=4*6
r=24

but that makes her mum 6? erm think i letters mixed up!?
possible r=6 and m=24

okay, confused………..
