While walking through a market on vacation, you notice a small stand selling cameras. A camera and case set is selling for $310. The seller tells you the camera costs $300 more than the case itself and the case costs the price of the set minus the cost of the camera.
You decide you`d rather wait on buying the camera and opt to just buy the case alone. You hand the seller a $100 bill and see his eyes light up. Think fast now. How much change should you be getting back.

Why would you buy a case for a camera you don't have?

BOB.T

Camera = $300
Case = $10
Therefore, change = $100 - $10 = $90

Either there's no real puzzle here at all, or I'm missing something.

How did those of you who said $95 get that figure?

SunnyGTIR

Camera $300 more than case.
Camera must be $305, case $5.

*mumbles something incoherently*

I really do hate puzzles like that. Its amazing how daft a human brain can be. Took me at least 10 mins to work out that it was not $90

So what's the answer?

If the answer really is $95, with the case costing just $5, what I can't understand is why do the retailer's eyes "light up", when he could have sold the thing for $10 by not having a confusing pricing formula?

I suspect the guy wasn't of Asian persuasian

95 it is .........

B-B

let x = camera y= case
x + y = 310
y = 310 - x
x = y + 300
Those are all given info.

Subs for x in equation
y = 310 - y - 300
2y = 10
y = 5
Therefore camera cost $305 and case $5
So change is $95

Do you work at AWE as a Nuclear Scientist

I'm impressed ....... xxxx

NotoriousREV

And the other kids in the class said you'd never use it in real life!

BOB.T

Who's round is it?

B-B, where are you getting 2y from

B-B

y = 310 - y -300

Move - y to other side of equation you have to add y to both sides
y + y = 310 - 300
2y = 10

Simple and FUN. Added bonus I have impressed you!

Can you get me a job there then?? Part time please. 3 mornings would suit.

BOB.T - You need more beer - will be much clearer........or you will care less!

Odds on

Bollocks. I gave the geezer a score.

BOB.T

Yeah whatever, for $5 it's gonna be a crap case anyway and if you don't have a camera, what's the point?!

B-B

Well if its a crap case then you definitely dont want to pay too much for it!!

Doesn't really matter how much change you should be given, you probably weren't given it all.

The hell with that: there's one like it EVERY week in the middle of our pub quiz. Usually simultaneous equations. I find them easier than the blasted anagrams he puts in

Oh yes, and that was only no 42 or so, and there`s 150 of them and they are getting harder. The strange thing is if you pay for the hints for this one it tells you that the differance in price is really $290.
